XML Catalog issue 18

[John Cowan <jcowan@reutershealth.com>]

# If we define delegation of system identifiers analagous to the way
# we define delegation of public identifiers, it will be possible
# for a catalog search to have only a public identifier. (See the
# text about override).
#
# Do we need to say that more explicitly. Where?

I think this is ill-formed.  Even if we don't have delegation of
system identifiers, we *already* make it possible for a catalog
search to have only a public identifier.  There may be an issue
hiding here, but I can't detect it.
