It assigns a new Xml Schema Set object to variable schemas, and calls this object's Add method to add a schema to the collection.

This program validates the XML document against the schema successfully.

However, when the user selects the XML document catalog1.xml, validation fails for the book element in the lines containing more than one title element.
