                     throws SAXException

   startElement in interface ContentHandler

   endElement

   public void endElement(String namespaceUri,
                          String localName,
                          String qName)
                   throws SAXException

   notationDecl

   public void notationDecl(String name,
                            String publicId,

                                  String notationName)

   Specified by:

   unparsedEntityDecl in interface DTDHandler

   resolveNamespacePrefix

   public String resolveNamespacePrefix(String prefix)

   Description copied from interface: ValidationContext

   Resolves a namespace prefix to the corresponding namespace URI. This method is used for validating QName, for example.

   If the prefix is "" (empty string), it indicates unprefixed value. The callee should resolved it as if it sees an unprefixed element, rather than unprefixed attribute.

   If the prefix is "xml", then the callee must resolve this prefix into "http://www.w3.org/XML/1998/namespace", as defined in the XML Namespace rec.

   Specified by:

   resolveNamespacePrefix in interface ValidationContext

   Following copied from interface: org.relaxng.datatype.ValidationContext

   Returns:

   namespace URI of this prefix. If the specified prefix is not declared, the implementation must return null.

   isUnparsedEntity

   public boolean isUnparsedEntity(String entityName)

   Description copied from interface: ValidationContext

   checks if an unparsed entity is declared with the specified name.

   Specified by:

   isUnparsedEntity in interface ValidationContext

   Following copied from interface: org.relaxng.datatype.ValidationContext

   Returns:

   true if DTD has an unparsed entity declaration for the specified name. false if otherwise.

   isNotation

   public boolean isNotation(String notationName)

   Description copied from interface: ValidationContext

   checks if a notation is declared with the specified name.

   Specified by:

   isNotation in interface ValidationContext

   Following copied from interface: org.relaxng.datatype.ValidationContext

   Returns:

   true if DTD has a notation declaration with the specified name. false if otherwise.

   onIDREF

   public void onIDREF(String uri,
                       String local,
                       Object token)

   Description copied from interface: IDContextProvider

   this method is called when an IDREF is found. It is the callee's responsibility to store it and checks the existance of corresponding IDs later. Note that due to the forward reference, it is not possible to perform this check when IDREF is found. It must be done separately after parsing the entire document.

   Specified by:

   onIDREF in interface IDContextProvider

   onID

   public boolean onID(String uri,
                       String local,
                       Object token)

   Description copied from interface: IDContextProvider

   this method is called when another ID is found to check whether this ID is already used or not. It is the callee's responsibility that stores ID and checks doubly defined ID.

   Specified by:

   onID in interface IDContextProvider

   Following copied from interface: com.sun.msv.grammar.IDContextProvider

   Parameters:

   symbolSpaceName - token has to be unique within the same symbol space, but two tokens can have the same name if they reside in different symbol spaces.

   Returns:

   true if there is no preceding ID of the same name; false if this name is already declared as ID.
