Hi,

The draft-ietf-simple-chat specification states that the 'nickname' extension defined by XCON (RFC 6501) should be used to convey the nickname in the conference event package. I think section 7.4 could clarify this a bit more, since the following may happen:

Alice joins the conference from multiple endpoints, but same AoR. The way the conference event payload is defined, there will be only one <user> element, because the 'entity' attribute needs to be unique and in the context of a SIP conference the entity most likely will be the user's AoR. There will be 2 <endpoint> elements, representing each of Alice's SIP clients, so putting the nickname there would IMHO make more sense.

Also, using XCON just for the nickname attribute may not be desired by some (that's me at least :-) ) so what about adding something along these lines to section 7.4? "A conference focus MAY choose to use the display-text element in the 'endpoint' or 'user' element to convey the user's nickname".

Regards,
