XML Catalogs might be a solution if your tools support them:

I think libxml, xsltproc, saxon, xalan, xerces, etc. support them.

All my METS are dead in the water with the government shutdown.  Anyone have any suggestions for validating METS with MODS till they turn the federal government back on?  The instance documents all link to loc.gov for the METS and MODS.  Going forward, what is a reliable entity for hosting the schema?
