I think that we should just require support for it. It really is massively useful and trivial to implement. One comment: the parser should turn relative system identifiers into absolute ones before calling this method. The parser has information about the location of the "current" entity (parameter entity!) that the SAX application will not (since SAX provides no DTD information).
