Validating Schematron Documents
By default, a Schematron schema is validated as you type. To change this, open the Preferences dialog box , go to , and deselect the Enable automatic validation option.
To validate a Schematron document manually, select the 
Validate action from the
Validation toolbar drop-down menu or the menu. When
Oxygen XML Editor validates a Schematron schema, it expands all the included modules so
the entire schema hierarchy is validated. The validation problems are highlighted directly in
the editor, making it easy to locate and fix any issues.
Oxygen XML Editor offers an error management mechanism capable of pinpointing errors in XPath expressions and in the included schema modules.
