This is one of the situations that public IDs were invented for.  Does
Xerces have the ability to resolve public IDs?  Somebody (name escapes me
at the moment) fairly recently wrote a set of classes that implements John
Cowan's XML Catalog proposal, which among other things allows the
remapping of SYSTEM as well as PUBLIC IDs.  If the implementor doesn't
chime in, take a look at http://www.xmlhack.com; IIRC it was written up as
a news item there.
