This method notifies the end of an entity. The DTD has the pseudo-name of "[dtd]" and parameter entity names start with '%'.

Note: Since the DTD is an entity, the handler will be notified of the end of the DTD entity by calling the endEntity method with the entity name "[dtd]" after calling the endDTD method.

param
