README

A feature complete implementation of an XSLT 1.0 ISO Schematron processor for the XSLT 1.0 query language binding.

About

This is a trimmed down version of the XSLT 1.0 processor of SchXslt. The processor is implemend as a series of XSLT transformation that transpile a ISO Schematron schema to an XSLT validation stylesheet. The validation stylesheet creates a SVRL report when applied to a document instance.

Transpiling a schema is done in three steps.

The stylesheet 1-include.xsl assembles a complete schema by resolving and internalizing external definitions. It acts on the sch:include and the sch:extends with a @href attribute.

The stylesheet 2-expand.xsl expands (instantiates) abstract rules and abstract patterns.

The stylesheet 3-transpile.xsl transpiles the schema to the XSLT validation stylesheet.

SchXslt Redux XSLT1 is a strict implementation of ISO Schematron. If you switch from a different implementation such as SchXslt or the "Skeleton" your schema files might not work as expected.

Feel free to contact me if you need help getting your Schematron standard-compliant.

Limitations

SchXslt Redux XSLT1 comes with the following limitations.

Schematron variables scoped to a phase or pattern are promoted to global XSLT variables.

Schematron variables cannot be used in the rule context expression. XSLT 1.0 forbids the use of variable references in match patterns.

The URI of the primary document is neither reported in the svrl:active-pattern/@documents, nor in the svrl:fired-rule/@document attribute. XSLT 1.0 does not provide a function to access the URI of a document..

Installation and Usage

The Github releases page provides a ZIP file with the processor stylesheets. Download and unzip the file in an appropriate location. Users of eXist and BaseX can download and import an EXPath package from the releases page, too.

Java users can use the artifact name.dmaus.schxslt.schxslt-redux-xslt1 from Maven Central.

PHP users can use the package schxslt/redux-xslt1 from Packagist. The package provides a class SchXslt\Xslt1\Locator with a getStylesheets() method that returns an array with the paths to the stylesheets.
