/* Reports a reference to an external parsed general entity.
The referenced entity is not automatically parsed.
The application can parse it immediately or later using
XML_ExternalEntityParserCreate.
The parser argument is the parser parsing the entity containing the reference;
it can be passed as the parser argument to XML_ExternalEntityParserCreate.
The systemId argument is the system identifier as specified in the entity declaration;
it will not be null.
The base argument is the system identifier that should be used as the base for
resolving systemId if systemId was relative; this is set by XML_SetBase;
it may be null.
The publicId argument is the public identifier as specified in the entity declaration,
or null if none was specified; the whitespace in the public identifier
will have been normalized as required by the XML spec.
The openEntityNames argument is a space-separated list of the names of the entities
that are open for the parse of this entity (including the name of the referenced
entity); this can be passed as the openEntityNames argument to
XML_ExternalEntityParserCreate; openEntityNames is valid only until the handler
returns, so if the referenced entity is to be parsed later, it must be copied.
The handler should return 0 if processing should not continue because of
a fatal error in the handling of the external entity.
In this case the calling parser will return an XML_ERROR_EXTERNAL_ENTITY_HANDLING
error.
Note that unlike other handlers the first argument is the parser, not userData. */
