If an application needs information about notations and unparsed entities, it can implement this interface and register an instance with TQXmlReader::setDTDHandler().
Note that this interface includes only those DTD events that the XML recommendation requires processors to report, i.e. notation and unparsed entity declarations using notationDecl() and unparsedEntityDecl() respectively.
The reader calls this function when it has parsed a notation declaration.
.PP
The argument \fIname\fR is the notation name, \fIpublicId\fR is the notation's public identifier and \fIsystemId\fR is the notation's system identifier.
.PP
If this function returns FALSE the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
The reader calls this function when it finds an unparsed entity declaration.

The argument \fIname\fR is the unparsed entity's name, \fIpublicId\fR is the entity's public identifier, \fIsystemId\fR is the entity's system identifier and \fInotationName\fR is the name of the associated notation.
