This is not needed. Xerces inserts itself using the third method Sun
specified, which is to have a MANIFEST/ file inside its jar file. If it's in
the path, it gets found and used.

No, it's not. There is nothing you need to do on 1.5 to use Xerces 2.7, but
since we don't need to use it at the moment, it's a moot point.
