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 (as opposed to a cryptic error code). This error message is provided to the user if an error is encountered during the validation stage.
Oxygen XML Editor plugin uses the Skeleton XSLT processor for validation and conforms with ISO Schematron or Schematron 1.5. It allows you to validate XML documents against Schematron schema or against combined RELAX NG / W3C XML Schema and Schematron.
The Schematron editor renders with dedicated coloring schemes the XPath expressions. To customize the coloring schemes, go to.
You can validate the content using the Validate action at any time. Another way to validate schemas is to check them against their own Schematron schema rules using External validation action.
