Validating XML Schema Documents
By default, XML Schema files are validated as you type. To change this, open the Preferences dialog box , go to , and disable the Enable automatic validation option.
To validate an XML Schema document manually, select the Validate action from the Validation toolbar drop-down menu or the XML menu. When Oxygen XML Editor plugin validates an XML Schema file, 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.
