Compared to other problems that I was (am) having, catalogs are 
*straightforward* to implement. All in all it takes you about
three days to implement.

Catalogs are very important concepts for other things as well. If
somebody
doesn't want to use catalogs, he doesn't have to. Allowing for catalogs
doesn't really complicate the specs of XML and doesn't make it more
difficult 
to learn it.

:-) Assuming that you know the tools and the programming language that
you are using, two or rather three weeks is a fair estimation for a
non-validating
XML processor with no support for catalogs and public identifiers. 

Yet another requirement is that we get a revision of spec with all the
missing productions (mostly S) included and some of the productions
fixed
and/or clearified.

* Strongly Agree *
