Perhaps.

But I note that in your use case, you don't really care about the
system id at all.  You really want to say "ignore the system id,
and as long as the DOCTYPE name is gcapaper, use dtd/gcapaper.dtd"
and this is precisely what the DOCTYPE entry in TR9401 does.

So perhaps we should add the DOCTYPE entry from TR9401 to XML Catalogs.
