  Hum, usually the XML catalog is the Right Way to do this,
rooted in /etc/xml/catalog it registers the resources locally
installed and is looked automatically by the library when a resource
need to be find.
  Now at the API level it is also possible to install a resolver
the signature is 
  xmlParserInputPtr xmlNoNetExternalEntityLoader(const char *URL,
                                                 const char *ID,
                                                xmlParserCtxtPtr ctxt);
 taken from the exemple of the resolver installed by xsltproc(.c)
when the nonet option is requested.
  Still the best is to make sure the document instances use the
canonical URLs and the public ID for the resources and have them
cleanly installed in the catalogs (like for DocBook on Linux distributions
nowadays).
