True. There is a request in for it to be added to mozilla. There is a
FormsPlayer activeX control that can run inside IE.

I'll laugh here, I haven't tried the "novell xforms preview ". Just from
reading the whitepaper and description I can tell it's not ready for me to
deploy. In any case, it's fall out from their purchase of .. that company
that makes SOAP tools.. Gee, can't recall.

Fortunately I can show a lot.

I have several clients heavily invested in Zope/DHTML/XML-RPC solutions.
Typically SQL data is extracted, processed and then dumped as xml to the
client via XML-RPC. On the client, XSLT translates the data into forms, or
tables (with sortable columns).

For submission, I validate the form, grab the values and stick them into an
Object, send that object via xml-rpc (appears as a dict to Zope).

It's all lots of fun, but I'm getting tired of writing the same code over
and over. I'd like a higher-level view of layout, validation, minimal
client-side logic and submission.

And, <select> is a non-windowed control on IE, so it doesn't play well with
pop-up divs.

I'd really like to switch to a XUL layout, with xforms.. But Luxor is too
big, X-smiles is has ugly xforms, etc..
