/**
  * <p>This class is used along with XMLEntityResolver to resolve entities.
  * Instead of passing publicId and systemId on the resolveEntity call, 
  * as is done with the SAX entity resolver, an object of type XMLResourceIdentifier
  * is passed.  By calling the getResourceIdentifierType() method the user can
  * determine which data members are available for inspection:</p>
  *
  * <table border='1'>
  * <tr>
  *  <td>ResourceIdentifierType</td>
  *  <td>Available Data Members</td>
  * </tr>
  * <tr>
  *  <td>SchemaGrammar</td>
  *  <td>schemaLocation, nameSpace & baseURI (current document)</td>
  * </tr>
  * <tr>
  *  <td>SchemaImport</td>
  *  <td>schemaLocation, nameSpace & baseURI (current document)</td>
  * </tr>
  * <tr>
  *  <td>SchemaInclude</td>
  *  <td>schemaLocation & baseURI (current document)</td>
  * </tr>
  * <tr>
  *  <td>SchemaRedefine</td>
  *  <td>schemaLocation & baseURI (current document)</td>
  * </tr>
  * <tr>
  *  <td>ExternalEntity</td>
  *  <td>systemId, publicId & baseURI (some items may be NULL)</td>
  * </tr>
  * </table>
  *
  * <p>The following resolver would provide the application
  * with a special character stream for the entity with the system
  * identifier "http://www.myhost.com/today":</p>
  *
  *<pre>
  * #include <xercesc/util/XMLEntityResolver.hpp>

  *      case XMLResourceIdentifier::SystemId: 
  *        if (XMLString::compareString(xmlri->getSystemId(), "http://www.myhost.com/today")) {
