Well, actually, all are committers for cocoon and I'm afraid that I'm
the lest active one among them :-|

Probably the right place for it, yes.

Oh, there's some extent of SOAP support in Cocoon. But you're right,
not integrated with form validation &c.

Yes, that is what we started to investigate. But lack of time and
other more pressing things came in the way.

There isn't anything on the architecture of chiba available so I have
no idea how closely related chiba to XForms support in Cocoon would
be.
For Cocoon, I see two different and in part unrelated areas:
a) populate the form
b) Given that the client does support XForms, migrate the existing
actions to be XForms based i.e. make them aware of the changed
communication protocol.
c) For clients that do not support XForms
c1) have XForms output translated to XHTML
c2) have the returned results transformed to an XML representation
like an XForms aware client would generate.
c3) validate the input
I'm currently working on decoupling sitemap components from the input
layer, making that plugable. I think it could help with b)
I think c2) would be easy. I'm not quite sure if suitable components
exist already. I believe I came across some that looked quite
promising but didn't investigate it any further.
For c3 it looked like that could be done by e.g. Xerces like you said
above.
Probably c1 is the most complicated part.
Chris.
