>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
