Subject: [Speechsc] Confusuion with INTERPRET

Does section 9.20 INTERPRET need some clarification? 9.20 states that INTERPRETATION should return an INTERPRETATION-COMPLETE event (as described in 9.21), but the example in section 9.20 shows the following response:

   S->C:    MRCP/2.0 49 543267 200 COMPLETE
           Channel-Identifier:32AECB23433801@speechrecog
           Completion-Cause:000 success
           Content-Type:application/nlsml+xml
           Content-Length:...

That S->C format is for responses (5.3), not events (5.5).  Contrast this with the RECOGNITION-RESPONSE event to RECOGNIZE:

   S->C:MRCP/2.0 486 RECOGNITION-COMPLETE 543260 COMPLETE
   Channel-Identifier:32AECB23433801@speechrecog
   Completion-Cause:000 success
   Waveform-URI:<http://web.media.com/session123/audio.wav>;
                size=124535;duration=2340
   Content-Type:applicationt/x-nlsml
   Content-Length:...

Shouldn't the first line of the INTERPRETATION-COMPLETE event be something like the following?
   S->C:    MRCP/2.0 49 INTERPRETATION-COMPLETE 543267 COMPLETE

The only mention of INTERPRETATION-COMPLETE in the spec are
* table of contents
* 9.3 Recognizer events
* 9.21 where it's described
* 13.1.2 MRCPv2 methods and events
* 15 Normative definition

I found no usage examples for INTERPRETATION-COMPLETE; most notably not in 9.20

Also, section 9.9 states
   For the recognizer resource, RECOGNIZE is the only request that
   returns a request-state of IN-PROGRESS, meaning that recognition is
   in progress.

But the example in 9.20 for INTERPRET shows
   S->C:    MRCP/2.0 49 543266 200 IN-PROGRESS
           Channel-Identifier:32AECB23433801@speechrecog

Is the recognizer resource the resource that performs interpretation?  If so, then the text in 9.9 should be changed to say the following:
   For the recognizer resource, RECOGNIZE and INTERPRET are the only
   requests that return a request-state of IN-PROGRESS, meaning that
   recognition or interpretation is in progress.
