Re: [Sip] MESSAGE for rendering

[Paul Kyzivat <[e-mail]>]

Hadriel,

I am entirely with you if the *intent* of sending the vcard is to render 
it to the user in some human readable way. Its hardly any different from 
sending HTML.

Its much more questionable if the intent is that the vcard be filed in 
the recipients address book without being rendered.

Even so, I think it is an open question whether content-dispositions 
other than "render" are valid with MESSAGE. And if so, which ones?

Not that I want to contradict myself on it being a valid use-case for INFO, but personally I'm not so sure that vcard/vcalendar is wrong for MESSAGE.  I mean we can argue if sending that type of data is really justification for an "Instant Message" request, but I'm talking more about whether content that isn't directly rendered to the user can be put into MESSAGE.

Just as, for example, a MESSAGE can contain message/cpim when we don't really expect to visibly render the message/cpim headers without interpretation.
