Where should PSGML find standard DTDs?

I've looked around and have not found a better set of DTDs for text
documents.  psgml-dtds covers HTML to 4.01, XHTML to 1.0, DocBook 3.1.
My own area has newer DTDs such as XHTML 1.1 and SVG 1.0 and 1.1.
Then there are DTDs that are used within my company only.

This does not seem to be the case for Windows / Cygwin.  The closest
that I managed was to install docbook packages which did the DTDs plus
an XML Catalog rooted at /etc/xml/catalog.  sgml-common does not seem
to be packaged for Cygwin; if it were (not too difficult I guess) then
it could be used to manage an Open Catalog rooted at
/etc/sgml/catalog.

My current setup is to use xemacs-packages and site-packages to keep
my various DTDs in.  Then I point xmllint at them using an XML catalog
that I edit manually (using PSGML :-).

ISTM that there is an opportunity for a catalog manager application
for local copies of DTDs, etc.  It might provide an Open Catalog for
PSGML and OpenSP, and an XML Catalog for libxml2, etc.  Maybe even
conversions to RNG, XSD, etc.  Does such a beast exist?  I'm going to
try out xmlcatmgr + Trang.


The bottom line for me is that psgml-dtds is still useful and I have
installed it in xemacs-packages.
