A catalog is just a map of URIs (and public ids, if you want) to other
URIs.  It's a standard format designed by OASIS, paralleling an earlier
SGML catalog standard.  It's supported by a number of parsers and
validators.

What more arguments do you want?  There are a number of ways this
*could* be done; doing it *this* way means it just works.
