ISO Schematron Implementations

Rick Jelliffe is currently testing the skeleton implementation of ISO Schematron. Currently this is expected for release in late January 2007.

ISO SVRL Implementations

SVRL is a simple XML language for reporting the results of Schematron validation. As an XML document, it is suitable for further styling and conversions.

Schematron 1.5 Reference Implementation for XSLT

The reference implementation is a software project based around skeleton1-5.xsl. It has been tried on 12 different and the test results are available on that page, togther with API documentation and samples of .BAT files for running the code with various XSLT processors.

Various tools include an error browser and a validator for interactive debugging in editors.

Schematron 1.5 tools are still being ported from 1.3. Some implementations at the Sinica site are pre-1.5 (see below). These are should be fine for schemas that just use patterns, rules, asserts, reports and names.

XML DTD for Schematron 1.5

A DTD for Schematron1.5. If possible, please use your own local or cached copy.

We do not recommend using the DTD except for document creation, because some implementations of XSLT do not handle relative file location correctly.

If you are not using namespace prefixes, put the following document type declaration at the top of your schema (after any XML declaration and stylesheet declaration):

<!DOCTYPE schema PUBLIC "http://www.ascc.net/xml/schematron"
   "http://www.ascc.net/xml/schematron/schematron1-5.dtd">

If you are using namespace prefixes, put the following document type declaration at the top of your schema (after any XML declaration and stylesheet declaration):

<!DOCTYPE sch:schema PUBLIC "http://www.ascc.net/xml/schematron"
   "http://www.ascc.net/xml/schematron/schematron1-5.dtd"
[
  <!ENTITY % sp "sch:">
