You won't make much progress if you think of it as message "requests"
and "responses". Think of it as resources with representations and
addresses. Can the representations be XML? Yes. Can you send AND receive
representations? Yes. Can addresses be XML? No, not easily. But if you
think of them as addresses, then it becomes less interesting to pack
information into them as if they were messages. Pop up a level and
figure out what you are trying to do, what you want to be addressable
and what you want to be the representation.

The good news is that manipulating representations of resources is *even
more exciting* than sending schema-valid XML messages.

XForms *does* have GET support.
