Detailed Description
Receive notification of basic DTD-related events.
If a SAX application needs information about notations and unparsed entities, then the application implements this interface and registers an instance with the SAX parser using the parser's setDTDHandler method. The parser uses the instance to report notation and unparsed entity declarations to the application.
The SAX parser may report these events in any order, regardless of the order in which the notations and unparsed entities were declared; however, all DTD events must be reported after the document handler's startDocument event, and before the first startElement event.
It is up to the application to store the information for future use (perhaps in a hash table or object tree). If the application encounters attributes of type "NOTATION", "ENTITY", or "ENTITIES", it can use the information that it obtained through this interface to find the entity and/or notation corresponding with the attribute value.
The HandlerBase class provides a default implementation of this interface, which simply ignores the events.

Receive notification of a notation declaration event.
It is up to the application to record the notation for later reference, if necessary.
If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application.
- Parameters:
-
| name | The notation name. |
| publicId | The notation's public identifier, or null if none was given. |
| systemId | The notation's system identifier, or null if none was given. |
- Exceptions:
-
| SAXException | Any SAX exception, possibly wrapping another exception. |

Reset the DocType object on its reuse.
This method helps in reseting the DTD object implementational defaults each time the DTD is begun.

Receive notification of an unparsed entity declaration event.
Note that the notation name corresponds to a notation reported by the notationDecl() event. It is up to the application to record the entity for later reference, if necessary.
If the system identifier is a URL, the parser must resolve it fully before passing it to the application.
- Exceptions:
-
| SAXException | Any SAX exception, possibly wrapping another exception. |
- Parameters:
-
| name | The unparsed entity's name. |
| publicId | The entity's public identifier, or null if none was given. |
| systemId | The entity's system identifier (it must always have one). |
| notationName | The name of the associated notation. |
