Greetings Waleed, if you feel that the XForms Core module is too coarse a granule to reuse for your purposes then perhaps you would like to look at the bind element and see if that would meet your need and if so why not provide feedback to the XForms group that you would like to see it as a module. XForms uses XML Schema as its basic type validation scheme upon which can be layered XForms constraints. The SChema types can be associated in three ways, the "normal" schema one of associating a schema with the document, the xsi:type approach or an xforms supplied feature of bind that allows at type to associated with a node in a manner similar to xsi:type but without having to change the document. Regards, Roland

It's my feeling that a language to express business rules deserves to be a first class citizen in the standards world. If the XForms workgroup considers expanding on their dynamic model (add rule grouping mechanisms, context-sensitive embedding in XSD, standardized error reporting ...etc) and branching out the effort into a separate standard that works equally well with XForms and with other standards, then that would be something wonderful.

That's the general plan. If there is enough similarity and compatibility, convergence makes a lot of sense. I'll study this in more detail. Thanks Mark and Rick for the pointers.
