1. What if you don't share presence with the other party and thereforecan't receive caps data? I assume you'd need to send a service discoveryrequest or share directed presence.
That is some thing we need to rework anyway, I think. IMO, when we don't share presence, we should send a directed presence directly after the first message - this should be a seperate XEP or even part of XMPP Messaging or Core. When we close the chat window (or manually using some button in the client), we could send an unavailable presence again - and also when we disconnect, of course. Same for invisibility. It is incredible annoying when someone who's invisible messages you and lots of stuff doesn't work therefore (like sending a file).
2. If you don't know (via disco/caps) that the other party supports XEP-0085, does the spec need to say that you (a) "MUST NOT" or (b) "SHOULD NOT" send chat state notifications?
A "MUST NOT" would mean all old clients break it, so I think a "SHOULD NOT" is better.
