java.lang.Object org.apache.xerces.impl.xs.XMLSchemaLoader
public class XMLSchemaLoader
This class implements xni.grammars.XMLGrammarLoader. It also serves as implementation of xs.XSLoader interface and DOMConfiguration interface. This class is designed to interact either with a proxy for a user application which wants to preparse schemas, or with our own Schema validator. It is hoped that none of these "external" classes will therefore need to communicate directly with XSDHandler in future.
This class only knows how to make XSDHandler do its thing. The caller must ensure that all its properties (schemaLocation, JAXPSchemaSource etc.) have been properly set.
