For the validation, shouldn't that be easy using Xerces? since most
of it is already supported.
If you only have a server-side validation yes, but I'd like to have
these validations done on the client-side as well, so it saves
roundtrips to the server
do you see any chance to achieve this on a browser client? i've
considered schema validations on the client as much too expensive up
to now. - please enlighten me ;)

Sorry, yes, this is what we discussed earlier by having the
schema-constraints and or some xforms constraints (e.g. length) be
converted to javascript calls in html with help from the xslt. e.g.
one-pass: schema -> schema2xforms -> xforms with all constraints -> xslt
-> html+javascript
two-pass: schema -> schema2xforms -> xforms with some constraints ->
xslt + original schema -> html+javascript
Which one is possible depends on the kind of constraints that can be put
in an xforms document. I think (but do not know xforms well enough) the
second option is needed. e.g. can a regexp like mentioned above be in an
xforms document, or not (which I assume, since an xforms document
already references a schema it's duplicate to put these contraits also
in the xforms document)
