_format
protected final OutputFormat _format
- The output format associated with this serializer. This will never
be a null reference. If no format was passed to the constructor,
the default one for this document type will be used. The format
object is never changed by the serializer.
_writer
protected Writer _writer
- The writer to which the document is written.
_dtdWriter
protected StringWriter _dtdWriter
- The DTD writer. When we switch to DTD mode, all output is
accumulated in this DTD writer. When we switch out of it,
the output is obtained as a string. Must not be reset to
null until we're done with the document.
_docWriter
protected Writer _docWriter
- Holds a reference to the document writer while we are
in DTD mode.
_exception
protected IOException _exception
- Holds the exception thrown by the serializer. Exceptions do not cause
the serializer to quit, but are held and one is thrown at the end.

and get the accumulated DTD, call
