Re: Is prefer useful?

Perhaps. In XML systems it's hard to imagine using it very often.
However,

1. It makes conversion of TR9401 catalogs easier
2. It makes XML Catalogs easier to use with SGML systems
3. Delegate discards the system identifier, so XML Catalogs are sometimes
   searched with only a public identifier.

                                        Be seeing you,
                                          norm
