Well, UC2 requires more or less to go MIME->XML as well, and all the fun
of headers continuation, implicit LWS, implementation that are not
accepting reformatting of some headers will surface because of this use
case.

Also, in the case of UC2 and HTTP resources, how will we handle the
content negotiation case if the sender embeds a format that the receiver
can't understand, but with a Vary header, should we require all
implementation that use this deferenciation scheme to act as fully
compliant HTTP/1.1 caches?
Thanks,
