Jurgen, I don't think that this is what Enrico is looking for.

What he wants is a document instance generator that given a schema
generates valid instances for that schema.

The closest thing that I am aware of is the annotated schema mechanism
of SQLServer, where you take a schema, annotate it against the database
tables and then use XPath expressions to get XML out according to the
schema. 

Enrico, what I find missing in your description is where the data that
will form the new document instance will come from. If from a database,
the approach above should be what you are looking for, if random of if
you just want a skeleton, you would have to write your own application,
as far as I know. 

HTH
