Applications may create a Schema with the validation API and associate it with a DocumentBuilderFactory or a SAXParserFactory instance by using the setSchema(Schema) and setSchema(Schema) methods. You should not both set a schema and call setValidating(true) on a parser factory. Tip: Use the global title attribute to describe the pattern to help the user. A number of frameworks provide some kind of validation capability that uses the notification pattern.
