I don't think that this problem is much worse than in HTML. The solution should probably be part of the public identifier resolution mechanism. XML doesn't currently specify a particular public identifier resolution mechanism (and it was a long and painful debate that isn't likely to be repeated!) but most likely a default mechanism will be specified in a separate proposal to the W3C (separate from XML). It will most likely be a catalog format that maps public identifiers (like URNs) to system identifiers (URLs) while we wait for a robust, global, automatic URN mechanism to come on-line. That catalog can allow multiple system identifiers to be associated with a single public identifier. Paul Prescod
