RE: [xml-dev] Can XML Schema be compiled to Schematron?

[Michael Brennan <Michael_Brennan@Allegis.com>]

I haven't dug deeply into this abstract schema model. But a cursory look looks like it is just an object model for XML Schema. It's does not look very generic to me. The W3C could learn a lot from the work that has happened in the RELAX and RELAX NG communities. Also, Schematron is not grammar-based, so you could not just do a straightforward mapping of an XML Schema grammar into Schematron. You would have to infer XPath patterns from the structure in the grammar since Schematron is pattern-based.

 

A far more interesting abstract schema model is in Sun's Multi-Schema Validator library. Check out http://www.sun.com/xml.

I suspect once there is full support for DOM Level3 Abstract Schema in Xerces Java 2, this may not be difficult. Once we create a Abstract Object Model for XML Schema, we can spit out Schematron-compliant schema.

I have been thinking that it would be an interesting exercise to implement a compiler that transforms XML Schema into Schematron (probably in XSLT). 

 

Is there any reason why this will not work?
