Abstract:
   RFC 6443 'Framework for Emergency Calling Using Internet Multimedia'
   describes how devices use the Internet to place emergency calls and
   how Public Safety Answering Points (PSAPs) handle Internet multimedia
   emergency calls natively.  The exchange of multimedia traffic for
   emergency services involves a SIP session establishment starting with
   a SIP INVITE that negotiates various parameters for that session.

   In some cases, however, the transmission of application data is all
   that is needed.  Examples of such environments include alerts issued
   by a temperature sensor, burglar alarm, or chemical spill sensor.
   Often these alerts are conveyed as one-shot data transmissions.
   These type of interactions are called 'data-only emergency calls'.
   This document describes a container for the data based on the Common
   Alerting Protocol (CAP) and its transmission using the SIP MESSAGE
   transaction.

Hi all,

James has been working in EENA on extensions for the additional data
draft and has also been playing around with code. As part of that
exercise he discovered bugs, which I like to bring to your attention.

As a high-level summary, we believe the following changes are needed
based on the bugs he discovered:
 * fixes to examples,
 * normative changes to the vcard XML schema found in the appendix, and
 * addition of a new IANA registry.

Here are the details:

-- Issue #1: James discovered a bug in Figure 17 of version -37 with
regard to the xc namespace prefix. Here is the snippet:

   <pi:DataProviderContact
   xmlns:xc=3D"urn:ietf:params:xml:ns:vcard-4.0">

This is a copy-and-paste error since the referenced schemas at
http://ip-emergency.net/additional-data.zip contain the correct instance
documents.

-- Issue #2: James noticed a problem with the value 'main-number' used
in the following example:

      <tel>
            <parameters>
               <type>
                  <text>work</text>
                  <text>voice</text>
                  <text>*main-number*</text>
               </type>
            </parameters>
            <uri>sips:john.doe@example.com <http://example.com></uri>
      </tel>

main-number is not a valid type according the schema from Section 6.4.1
of RFC 6351. RFC 6351 lists the valid types as:

  * =E2=80=9Cwork"
  * =E2=80=9Chome"
  * =E2=80=9Ctext"
  * =E2=80=9Cvoice"
  * =E2=80=9Cfax"
  * =E2=80=9Ccell"
  * =E2=80=9Cvideo"
  * =E2=80=9Dpager"
  * "textphone"

This looks like a minor issue since we already state in the text that
'main-number' is a new value this draft introduces. However, the way the
XML schema in RFC 6351 is defined you cannot just add values since it
contains an enumeration with a fixed list of values.

The reason we have not noticed this earlier is because the example in
Figure 17 the content of the zip file is again out of sync with what is
in the draft. The example in the zip file does not contain the text
main-number and hence no error shows up. Of course, if I use the
main-number (as shown in the body of the draft) then an error is thrown.

Needless to say that this is a problem.

What can we do about this?

Currently, the XML schema in Appendix A is informative and the Relax NG
schema in RFC 6351 is normative.

We can make the XSD schema currently found in Appendix A normative and,
at least, add this new value (main-number). Then,
there is the question whether this will be the only value ever added. If
so, then it is fine to add it to the enumeration. If it is not then we
need to go a different path, namely to just declare it as a string and
register the values with IANA.

Because of this normative change we need to reach out to you. If you
have other suggestions on what we should do please let us know!

Ciao
Hannes

It is also worth noting that we will require a new namespace for the cad sch=
ema if we make it normative and update the examples accordingly.

The solution detailed by Hannes is a fine one, and is the approach 
I'd recommend if the draft was earlier in the process.  Given the 
late stage, my preference is to make minimal changes to the draft. 
The minimalist approach would be the following:

    (1) fix the example to use 'main-number'
    (2) fix the xCard schema in Appendix A to add 'main-number' to the 
list of values
    (3) in the text in Section 4 that normatively adds 'main-number' 
to xCard, add an explanatory note that this new value is added in the 
xCard schema in the document but does not appear in RFC 6351, and 
note that should additional values be needed in the future, a new 
IANA registry of the values is recommended
    (4) in Appendix A, add a note that the schema is a simplified 
version of RFC 6351 with the addition of 'main-number'

These changes are a way to fix the document with the least impact. 
There is no requirement that XML schemas in RFCs be normative since 
the text is always normative.  There is no requirement to add an IANA 
registry when a list of strings is expanded.  In new documents, it is 
cleaner and better to do both, but to fix late-stage bugs we can skip 
both.

I totally disagree with this approach and the argument that the document =
is far progressed not a reasonable excuse for publishing a document that =
has clear issues.

The approach below results in two different schemas with the same =
namespace one of which is considered normative and the other informative =
yet the additional-data specification will require use of the =
informative schema.

What is the issue with altering the schema to accommodate what we want, =
move the undesirable token sets into a repository, change the namespace =
and making it normative?
This ensures integrity of namespaces, it doesn=E2=80=99t really =
structurally change the document, but it does result in a much better =
outcome.

Cheers
James

There is no requirement that XML schemas in RFCs be normative since the =
text is always normative.  There is no requirement to add an IANA =
registry when a list of strings is expanded.  In new documents, it is =
cleaner and better to do both, but to fix late-stage bugs we can skip =
both.

James is right here.  An implementation of RFC 6351 will choke on this
new value.

The correct way to address this is to make a new schema that patches
the RFC 6351 schema.  In relax NG that's easy [1], because you only
have to redefine "property-tel".  But you do need to give it a new
namespace.  An XML schema is tough.

I never said to publish a document with defects.  I was proposing one 
approach to solve the defects without opening up a lot of new work.

So we also need to add a new namespace for the corrected schema.

I said that was the cleaner approach, and one I'd take with a new 
document.  I just don't think we need to do all those steps now.

One might say that the right's approach is to release the dogs of the
market, throwing all traditional values into disarray; and then, in
this tumult of insecurity, offer themselves up as the last bastion of
order and hierarchy, the stalwart defenders of the authority of
churches and fathers against the barbarians they have themselves
unleashed.  A scam it may be, but it is a remarkably effective one;
and one result is that the right ends up seeming to have a monopoly on
value.  --David Graeber, "Army of Altruists", Harper's, January 2007.

[AJW] I don=E2=80=99t think that it is a question of =E2=80=9Cneed to do =
all those steps now=E2=80=9D. If we don=E2=80=99t do them, then they are =
not done. This isn=E2=80=99t something that we are going to go and clean =
up later. We aren=E2=80=99t going to change the structure, or even make =
other corrections that I would dearly love to see. We are just going to =
change the name space, change an enumeration into a token that is filled =
from a repository, and make the schema normative. Small changes, but =
will allow the document to move forward in a clean fashion.

FYI: I asked Philip, who discovered issues with the schema end of last
year, for feedback on this topic. See below.

Hannes,

Issue 1:
It looks like:

<pi:DataProviderContact xmlns:xc=3D"urn:ietf:params:xml:ns:vcard-4.0">

needs to be changed to:

<pi:DataProviderContact xmlns:"urn:ietf:params:xml:ns:vcard-4.0">

If I am interpreting the issue correctly then this is a simple editorial
change that should be done.

Issue 2:
I think the simplest thing to do is to make the XSD schema in Appendix A
normative and then add the "main-number" value to the enumeration.

Regards,
Philip H. Reichl

We would still have to change the namespace.

This sounds reasonable to me.  We also won't need to change the namespace.

I think that the general approach is okay, I remain unconvinced that we =
don=E2=80=99t need a new namespace however, because the schema in RFC =
6351 is normative and it has an error and our solution requires the =
error be corrected.

Cheers
James

So, just make sure I am clear on what the plan is:
1) Remove the enumeration for the schema so all values now come from the =
registry only
2) Add main number to the registry
3) Change the namespace
4) Update all examples to use the new namespace
5) register the namespace and schema with IANA

Cheers
James

Thanks for listing the steps, James.

Hannes, does this sound like the plan to you?

Brian, do you concur?

Thanks everyone.

Hi Dan,

thanks a lot for your feedback. I did not check the errata and therefore
failed to notice that this issue already surfaced earlier.

Ciao

Hi Randy, Hi James,

I'm not entirely sure this is the right way to go.

First, if the values can only come from the registry, that still excludes t=
he x-name values (which seems to me to be nearly as big of an omission as l=
eaving out the iana-token values).

Second, is changing the namespace really necessary?  Perhaps I don't unders=
tand the errata process correctly, but James' argument that the RFC 6351 sc=
hema error requires it does not seem persuasive to me in light of the exist=
ing errata already being verified status (as opposed to held for update).  =
That suggests to me that any RFC 6351 implementation should take this errat=
a into account.

Changing the namespace also brings new complications: the xCards will not b=
e interoperable with an RFC 6351 implementation (even one that considers th=
e errata), and the Appendix A schema would have to be normative.  This esse=
ntially redefines the entire xCard schema with an XML schema when the previ=
ous version was a Relax NG schema.  This doesn't seem like a good idea to m=
e.

Hi Randy, Hi James,

the proposal makes sense to me an I have been working on an update to refle=

Hi Dan,

The =E2=80=9Cheld for update=E2=80=9D status is used for issues found =
that are not necessary for an update to the RFC, so =E2=80=9Cverified=E2=80=
=9D is the only status available that fits the problem. It isn=E2=80=99t =
clear to me that this means that it is okay to make changes to the =
schema in a registered namespace, it just says that the errata should be =
available to implementors. That is to say does the errata say =E2=80=9Cbe =
aware=E2=80=9D of the limitation that shouldn=E2=80=99t be there or fix =
the schema in the current namespace and move on? I think that the Errata =
status definitions could be more clear on this. I am not keen in just =
changing bits of a registered schema because there are errors and =
leaving it in the same namespace, this will certainly lead to =
implementation errors.

In the changes that have just gone in, the XML has moved to being =
normative and it spells out that it is for additional-data, so while =
x-names might be useful in a straight vCard, I question their =
applicability to the additional-data work.

To my mind the approach we have taken is unambiguous, where suppositions =
about what the errata actual means could lead to problems.

Cheers
James

This is an OpenPGP/MIME signed message (RFC 4880 and 3156)

Hi Dan,

the situation looks a bit tricky.

It seems that accepting the errata wasn't quite the right thing since it
changes an XML schema without defining a new namespace and without
registering the new schema.

In some sense, we could be equally "relaxed" and just change their
schema again (without changing the namespace).

I believe it ultimately boils down to the question what the value of the
XML schema actually is.

I see a couple of different usages:

a) If someone uses the XML schema to generate code then anything other
than defining our own, corrected XML schema will lead to problems

b) If the XML schema is only used by an implementer to validate instance
documents than defining our own, corrected XML schema will also be needed=
=2E

c) If the XML schema is, however, only used as a different way of
reading the document content then changing the schema within the text
(as we had done up to version -37) is fine.

I personally think that most developers don't do (a) and (b) and that's
why most of the XML schemas in technical specifications are actually
broken (not only in the IETF but also elsewhere). The "most developers"
is important here since we have found developers, such as Philip, who
actually produce code based on the schema (which is why he found problems=
).

However, by making these types of "fixes" we are obviously not going to
improve the situation. It is also the question what the IESG and the
area directors think about this situation. In some sense it is not only
about the use of XML schemas but the issue is a bit more broadly related
to the use of formal languages in the IETF in general. There are many
other places where we messed things up, such as with ABNF.

Ultimately, it fear it will boil down to a different question, namely:
What does it mean if the VCard schema in our spec is different from the
original VCard schema in terms of re-use with existing software.

Ciao
Hannes

Hi all,

it seems that our discussions on the additional data draft cannot be
settled before the submission deadline. For this reason I prefer not to
upload a new version yet.

There is, however, a version in the Github repository where we made
changes to the XML schema and this draft version can be found at:
https://raw.githubusercontent.com/hannestschofenig/tschofenig-ids/master/=
additional-data/draft-ietf-ecrit-additional-data-38.txt

The diff to version -37 can be found at:
http://tools.ietf.org//rfcdiff?url1=3Dhttps://tools.ietf.org/id/draft-iet=
f-ecrit-additional-data-37.txt&url2=3Dhttps://raw.githubusercontent.com/h=
annestschofenig/tschofenig-ids/master/additional-data/draft-ietf-ecrit-ad=
ditional-data-38.txt

I don't know how my other co-authors see this issue.

Ciao
Hannes

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Emergency Context Resolution with Internet Technologies of the IETF.

        Title           : A LoST extension to return complete and similar location info
        Authors         : Roger Marshall
                          Jeff Martin
                          Brian Rosen
	Filename        : draft-ietf-ecrit-similar-location-02.txt
	Pages           : 16
	Date            : 2016-03-21

Abstract:
   This document introduces a new way to provide returned location
   information in LoST responses that is either of a completed or
   similar form to the original input civic location, based on whether
   valid or invalid civic address elements are returned within the
   findServiceResponse message.  This document defines a new extension
   to the findServiceResponse message within the LoST protocol [RFC5222]
   that enables the LoST protocol to return a completed civic address
   element set for a valid location response, and one or more suggested
   sets of similar location information for invalid LoST responses.
   These two types of civic addresses are referred to as either
   "complete location" or "similar location", and are included as a
   compilation of CAtype xml elements within the existing LoST
   findServiceResponse message structure.

So, I think we have three remaining open questions, which are:

Should we go with -38 as it is (new namespace and schema normative) or

(1) Revert namespace to original name?
(2) Revert schema to informative?
(3) Do we add to the schema "x-" and "vnd-" tokens as well as IANA tokens?

Hi Roger,

One suggested very minor tweak in the wording: change "is not 
scheduled to" to "may not".

Hello,

"Given that 3GPP is not scheduled to finish their stage-3 work for eCall in=
 IMS until June 2017, as part of Release 14" is based on obsolete informati=
on.

Be aware that 3GPP CT approved a work item on "CT aspects of evolution to a=
nd interworking with eCall in IMS" (WID: http://www.3gpp.org/ftp/tsg_ct/TSG=
_CT/TSGC_71_Goteborg/Docs/CP-160053.zip). This includes CT1 work.

This work item is scheduled to be completed in September 2016 - see section=
 10 of the WID.

June 2017 is the final end of 3GPP Release 14, however some of the work ite=
ms will be finalized long before that.

Kind regards

Ivo Sedlacek

Hi Roger,

One suggested very minor tweak in the wording: change "is not scheduled to"=
 to "may not".

You don't think that that is a little rich when we asked them for their opin=
ion they said please wait and we say no, we are going ahead anyway?

It seems to me that we should be prepared to adapt.

I think it's best to not try and convey such messages in liaison

>From my knowledge of the 3GPP work so far (essentially the stage 1 service =
requirements) I would note at least some things with this draft:

1)	The service URN is meant to identify the resource that is required by th=
e requesting user. In a 3GPP environment that resource will be an entity th=
at supports both some data means of transmission (I can guess it will somet=
imes be a body but that discussion has not reached that point yet), but wil=
l also be required to support an in-band form of the existing CS supported =
MSD. This is for interoperability and migration purposes. Any URN that does=
 not identify support of both resources cannot be used in a 3GPP environmen=
t.

2)	Roaming is important in 3GPP. Some countries do not support ecall (and t=
herefore do not provided dedicated ecall PSAPs). The proposed URNs will the=
refore, by virtue of stripping unrecognized subtypes, end up on the normal =
PSAPs. That could be OK if there is a voice media included. However there i=
s a data only case in ecall which will not be directly usable by a standard=
 PSAP - it will essentially be a silent emergency call. Note that the attit=
ude of regulatory authorities to calls they cannot handle varies from count=
ry to country (some countries might even prosecute the generator of such ca=
lls). Mechanisms may need to be in place to prevent such ecalls when in reg=
ulatory regimes where ecall is not supported.

3)	The 3GPP requirements for test calls are not yet clear (at least to me).=
 What is clear is that if they are treated as normal calls then they will n=
ot "MNOs can treat a vehicle call in the "test" service URN in a way that t=
ests as much functionality as desired" because much of the network equipmen=
t will not be the same. Further for a roaming user, the test call may not e=
ven succeed. Further it is not yet clear (to me) whether all 3GPP ecall equ=
ipment and network providers will support non-emergency calls from an ecall=
 device.

Given that resolving these will be different from any published IETF docume=
nt based on the current draft and may well cause deployment problems in som=
e regulatory areas if the current IETF document is implemented, my proposal=
 is simple...

Regards

Keith Drage

Hi Randy,

I believe we should reach out to the IESG and ask them a question about
their approach regarding formal languages and the use of data definition
languages in particular.

It seems that we are not particularly lucky in the IETF with the use of
formal languages for describing protocol exchanges. While we excessively
use them we often get them wrong for a number of reasons.

In this specific case it seems that the authors of the XML xcard spec
got it wrong and fixed the bug in a way that is also violating the way
how these formal language is supposed to work. The correct way IMHO
would have been to issue a new schema (+ new namespace + new schema
registration). For whatever reason they haven't gone that route.

Now, for us the question is why cannot we cheat here as well?
Or, to phrase it differently, does anyone even care about these data
definition languages at all in IETF documents.

Ciao
Hannes

Hi Hannes,

I agree with you that formal languages have been a problem in our 
documents for decades.  In the particular case of additional-data and 
xCard, you are right that we already have two schemas using the same 
namespace, so the question is, should we do one more, or not?  I 
believe Dan has said he sees more problems if we define a new 
namespace then if we don't, but James disagrees.
