Editing Schematron Schemas

Schematron is a simple and powerful Structural Schema Language for making assertions about patterns found in XML documents. It relies almost entirely on XPath query patterns for defining rules and checks. Schematron validation rules allow you to specify a meaningful error message. This error message is provided to you if an error is encountered during the validation stage.

The Skeleton XSLT processor is used for validation and conforms with ISO Schematron or Schematron 1.5. It allows you to validate XML documents against Schematron schemas or against combined RELAX NG / W3C XML Schema and Schematron.

Oxygen XML Editor assists you in editing Schematron documents with schema-based content completion, syntax highlight, search and refactor actions, and dedicated icons for the Outline view. You can create a new Schematron schema using one of the Schematron templates available in the New Document wizard.

You can specify the query language binding to be used in the Schematron schema by doing the following:

For embedded ISO schematron, open the Preferences dialog box, go to XML > XML Parser > Schematron, and select it in the Embedded rules query language binding option.
For standalone ISO Schematron, specify the version by setting the query language to be used in a queryBinding attribute on the schema root element. For more information see the Query Language Binding section of the Schematron specifications.
For Schematron 1.5 (standalone and embedded), open the Preferences dialog box, go to XML > XML Parser > Schematron, and select the version in the XPath Version option.

The Schematron editor renders the XPath expressions with dedicated coloring schemes . To customize the coloring schemes, open the Preferences dialog box and go to Editor > Syntax Highlight.

Note: When you create a Schematron document, Oxygen XML Editor provides a built-in transformation scenario. You are able to use this scenario to obtain the XSLT style-sheet corresponding to the Schematron schema. You can apply this XSLT stylesheet to XML documents to obtain the Schematron validation results.
