public class XSDHandler
extends java.lang.Object

The purpose of this class is to co-ordinate the construction of a grammar object corresponding to a schema. To do this, it must be prepared to parse several schema documents (for instance if the schema document originally referred to contains or information items). If any of the schemas imports a schema, other grammars may be constructed as a side-effect.
