Public to system, system to system.

You don't.

The purpose of catalogs is to prevent your web server from being
hammered by millions of sites all trying to download your DTD to
validate your widely distributed documents.

With catalog technology widely disseminated, this is not necessary.
Each site can make a local copy of the DTD, and then use a local catalog
to map the central, standardized URI to a local URI or file name.

Futhermore, you can exploit Formal Public Identifiers to give DTDs
and the like long, meaningful names that don't depend on the vagaries
of the DNS.

I'm totally in sympathy with this.
