For those that don't have an XmlAppBase, the "noop" operation in this
case would be:

public String resolveEntity (String ename, String publicID, String
systemID){
	return systemID;
}

Of course this default behaviour cannot be specified in CORBA, but it
can be specified in the SAX documentation, so I don't think that it is a
big deal.

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).
