[oXygen-user] Help on XForms validation and auto-completion

Hi Paul,

There are a couple of approaches to have XHTML plus XForms validation 
and content completion.
As far as I know there is under development at W3C an XML Schema that 
handles XHTML and XForms. Not sure how to access that though... I will 
see what I can find out about that and let you know. This will give you 
both content completion and validation as with any XML Schemata.
Another approach is to use NVDL or NRL schema to combine the XML Schema 
for XForms and the Relax NG schema for XHTML. Makoto has such a sample 
NRL schema here:
and IIRC an NVDL schema for XHTML + XForms is presented in the NVDL 
specification. oXygen has support for NRL and the NVDL support can be 
added as external tool. This will give you validation but not content 
completion - we plan to support NRL/NVDL also for content completion in 
the future.

Best Regards,
