Re: writing a DTD with TDTD and using it with psgml

Why not just use 
  <!DOCTYPE book SYSTEM "tutorial.dtd">
while you're doing your experimentation?  Ie. referring to a DTD in
the same directory as the document?

You don't have to extend the catalog.  One thing I do is to have
"catalog", and "CATALOG" in my SGML_CATALOG_FILES variable, eg.
   export SGML_CATALOG_FILES="catalog:CATALOG:/etc/sgml/catalog"

This will make psgml pick up files called "catalog" or "CATALOG" in
the document directory and use what it finds there.

What I do a lot for my own DTDs, is to create a CATALOG in the same
directory as the DTDs, mapping from PUBLIC identifiers to files, and
then I put a "catalog" file in the same directory as the documents
using the DTD, containing just the single entry:
  CATALOG "../../path/to/catalog"

That gives me a single point of change for the mapping to the DTDs.
