For a sufficiently generous interpretation of "as was intended", I
suppose you can get REST through.  I still wonder about REST in relation
to sections 2.4, 2.5, 3, and 4, once HTTP is used outside of the
user-controlled browser environment.

That's what a lot of people have said about XML.  I'm still not worried.

>HTTP gives you those, and it lets you use XML.

HTTP gives you a small set of verbs for application semantics.  If you
like HTTP's verbs, great.  If you just want to send messages, HTTP's
verbs may not be interesting.  If you want more verbs than HTTP has -
risky to be sure but appropriate in some environments - you also need to
look elsewhere.

"Lets you use XML" is not much of an issue these days.
