Subject: [Simple] Event Filtering Issue 3: Domain filter vs. resource filter

Some situations may arise where a subscriber may want to create a filter for a domain where the subscription may be fanned out to, but override it with a filter to a specific resource.

In this following example, a filter is set for example.com and for [email-masked] that overrides the domain filter.

<?xml version="1.0" encoding="UTF-8"?>
      <filter-set xmlns="urn:ietf:params:xml:ns:simple-filter"
                         xmlns:pidf="urn:ietf:params:xml:ns:pidf">
            <filter id="8439" uri="sip:example1.com">
               <what>
       	     <include>//pidf:tuple/pidf:status/pidf:basic</include>
   		</what>
            </filter>
            <filter id="999" uri="sip:[email-masked]">
               <what>
       	    <include type="namespace">urn:ietf:params:xml:ns:pidf</include>
       	    <exclude>//pidf:tuple/pidf:note</exclude>
   		</what>
            </filter>
      </filter-set>

There were no objections to this behaviour in the interim. If there aren't any objections on the mailing list, I will add some clarification text on this issue.

Regards,
Hisham
