Interesting thread. I would agree not to reinvent the wheel in terms of schematron. What I hear from clients and would like to see myself is a way to add the schematron-like constraints to a schema and validate in one pass. As it is now, it takes 2 passes to validate. Once for the schema and another to validate the additional constraints. If the "hooks" you mention would lead parser writers to incorporate validation of both of these in one pass, then I would say "yea!".

Rather than the XML Schema working group essentially reinventing a less-powerful version of Schematron, wouldn't it be more beneficial to the marketplace if the XML Schema working group created standard "hooks" for inclusion of Schematron patterns/rules/assertions? Then a user has the option of implementing data validation requirements either by embedding Schematron into an XML Schema, or keeping the schemas separate in a pipeline fashion. And hey XML Schema working group, how about also creating standard hooks for inclusion of other schema languages, such as Relax NG and RefleX? And how about supporting a building block approach to implementing data validation requirements? Rick Jelliffe, how about jumping into this discussion? /Roger _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
