Hello Aurelien,
See my response embedded below.  Thanks for reading the draft and providing your input.
ps - I've cc'd the dmsp list on my response, as there are others there who have made similar suggestions.

Hi Jonathan, 

I've read the specification of the EMMA at the W3C, and I wonder how we can insert the EMMA messages in the 
DMSP protocol. My view is that EMMA should describe the recognition results for example from the server to the client in 

a DSMP response MESSAGE. Is DSMP should really encapsulates EMMA messages ?  

JRE: Yes.  EMMA messages could be carried as "extended recognition results".  See section in the spec. 

DSMP messages are really closed to VoiceXML events / commands (NOINPUT, NOMATCH,...). Multimodal services can be done without VoiceXML browser (without VXML scripts) with only simple ASR/TTS ressources (only launch recognition or synthesis process). Do you plan to open / enlarge the DMSP protocol to "simple" Voice server (ASR+TTS without VoiceXML) ?   

JRE: We intentionally designed the protocol to operate at the dialog level, as this helps keep the protocol amenable to implementations that involve low bandwidth, high latency networks and resource constrained clients.   That said, you aren't the first one to bring this point up both on the mailing list and in offline discussions.  If there are additional features required by the particular multimodal use cases you have in mind that aren't already adequately addressed by MRCP,  please share them on the dmsp list.    We would like to maintain support for dialog level control messages, but at the same time are open to supporting other configurations as well, as long as we can keep the message set and associated state machines simple and compact. 

Thanks for your response, 
Best Regards.
