Title: XML Schema views - are they possible?
Cool.
Did
you address the problem of having multiple layers of abstraction and
the
use of global elements that forces one to use namespaces? GJXDM
is
wrestling with this one.

>I'm wondering is there a
possibility of having different XML Schema views (for reusability purposes).
I did a paper titled "Maintaining Schemas for Pipelined Stages" (http://www.snee.com/bob/docs/04-01-05.html) at
XML 2002 that addresses this problem. It uses hypothetical small examples, but
Eric van der Vlist has since told me that he has used its ideas in a
production system since then.
Instead of writing the schema as an XSLT stylesheet, as
Michael Kay suggests, my approach uses a master schema describing the shared
and unshared parts of the schemas in question and then a generic stylesheet to
pull out a schema (which one could call a "view") for a specific stage in the
pipeline as needed.
And it works with both W3C Schema and RELAX
NG.
