This is more for the RAI ADs than anything else (no action requested from the document authors). In 2. Security Considerations Advertising an endpoint's XMPP address over SIP could inform malicious entities about an alternative attack vector. Because the "purpose" header field parameter could be spoofed, the receiving endpoint ought to check the value against an authoritative source such as a user directory. Clients can integrity protect and encrypt this header field using end-to-end mechanisms such as S/MIME or hop- by-hop mechanisms such as TLS. We're talking about a SIP client (with an XMPP address in a SIP header field parameter), is that right? Has S/MIME gotten much deployment to date? I know we didn't even mention S/MIME in SIPconnect 1.1 (http://www.sipforum.org/component/option,com_docman/task,doc_download/gid,476/Itemid,261/)
