If the system IDs point to the XML IDs, then you don't need to add the
"wrong" public ID to the docbook-xml catalog. Following the
specification [1] system IDs are preferred over public IDs if both
exist. So the tools should automatically choose the XML DTDs for e.g.
validation.

Answer sent to docbook-apps. I don't think, the docbook list is the
appropriate place for such issues.
