Note The XML data is loaded into the DOM despite schema validation errors unless your Validation Event Handler raises an exception to stop the process.

If a Validation Event Handler was assigned to the Xml Reader Settings instance, or passed to the Validate method of the Xml Document class, the Validation Event Handler will handle schema validation errors; otherwise an Xml Schema Validation Exception is raised when a schema validation error is encountered.

XSD (XML Schema Definition Language) is the W3C recommended language for describing and validating XML documents.

SQL Server implements XSD as XML Schema Collections.

To validate the XML in the DOM, you can validate the XML as it is loaded into the DOM by passing a schema-validating Xml Reader to the Load method of the Xml Document class, or validate a previously unvalidated XML document in the DOM using the Validate method of the Xml Document class.
