Syntax-wise it looks right. Semantically RFC 4770 seems to be declaring
it as an IM or a presence address only.

So I am wondering if this could be source of confusion for non-sixpac
clients.

An example on page 2 seems to explicitly point that a SIP uri would be
used for SIMPLE chats and presence, and it is my understanding that most
sixpac clients would be unreachable this way.

Cheers,
