Re: [docbook-apps] basic catalog question

["Bob Stayton" <bobs@sagehill.net>]

Hi Craig,
I'm also a little confused by your example.  You named your catalog file 
"catalog.dtd", and you are trying to validate it against a DTD (as declared 
in your DOCTYPE) also named "catalog.dtd".  Are those the same file?  If so, 
that isn't the correct approach.  There is a DTD for XML catalogs available 
from OASIS that defines the catalog elements, but it isn't clear that is 
what you are using here.

BTW,
