   Re: [xml-dev] schematron for xml schema validation

[ Lists Home | Date Index | Thread Index ]

Hi Paul,
Sounds interesting and like a reasonable subject for a presentation,
but what I meant by "controlling the Schematron
 elegantly across a set of schemas" was the need to control Schematron
behavior across a set of XML Schemas, i.e. the external documents
requirement but from the starting point of being able to define a set
of xml schemas to operate across and having the schematron schemas
applied across the set but also interact within the set - perhaps via
an extension mechanism or by having a dsl for controlling the sets. I
have actually received a mail that was close to my requirements, but
it was not publically sent to xml-dev. maybe not ready for announcing
their project yet.
