RE: CreateNewInstance" from xml(Schema)

You could always map to relational tables that just contain empty
instances so a query would give you a pseudo-skeleton. But writing an
XSLT stylesheet is probably not much more hassle. Maybe somebody on this
or the XSLT list already did something like this...
