form representation in XML

[Angus Parvis]

Hi,

I'm working on an application, that has to represent forms both on
browser-clients (HTML, WML, whatever) and mobiles (using a VoiceXML
application).
For the browsers information like the name and possible values of a
field are enough - but VoiceXML requires an additional description of
the text field.

Now I'm looking for an existing XML-based form-standard, that fits my
needs. I read about XForms, but they don't seem to be useful - for
browser-based applications it's seems to be ok, but as far as i know, it
does not offer additional fields, as i would need them in VoiceXML.

Thanks for your help,

Angus
