Public Identifiers

[John Cowan]

Paul Prescod scripsit:

> If the author has said explcitly "Here is where to find

> the target of the reference (in the filesystem, at the HTTP server, etc.).

Sometimes, however, the user of the document knows better than the
author.  For example, a downloaded document with relative links can
benefit from an *ad hoc* catalog that expands them.  Similarly,
a *pro forma* SystemId on an overworked server may be usefully
converted to a local cached copy.

> In other words, I think that the SYSTEM declaration in SOCAT is probably a
> bad idea.

I take a more limited view:  "Avoid SYSTEM entries in publicly available
catalogs."
