Schema reporting tools - XQuery use case?

[ricardo queiros]

Hi,
I develop a tool for browsing XML Schema files in a easy way.
The tool calls http://x-query.com/mailman/listinfo/talk and can be downloaded as open source at
http://www.dcc.fc.up.pt/schemaDoc/.
It is based on a XSLT file that transforms the schema file in XHTML code to
be interpreted in a general browser.
So the only requirement is a web browser.

At this moment the tool don't support a few elements of the W3C XML Schema
specification (e.g. *field, key, keyref, redefine, selector, unique *elements
and *abstract, substitutionGroup *attributtes). It supports Schematron.rules
embeded in the schema file.

Best regards.
