oXygen and NVDL with XForms - adding support for the class attribute

This may be useful to others too. I've been using oXygen to edit XForms for a while now and I've found the NVDL validation to be incredibly useful.

One of the things that was bugging me for a while was that the schema threw errors every time I used a class="{nameofyourclass}" attribute on any <xforms: ...> element.

As my XForms get bigger and more complex, it's become frustratingly difficult to see the 'serious' structural errors because of the number of errors that complained about me using class attributes. So with a slight schema modification, we can get NVDL to allow for the use of classes..
