  I have been packaging xhtml1 DTDs for Red hat and related Linux
distribution for a decade or so. One thing that the W3C system team
could do is proactively provide catalogs updates that could be added
for all sorts of DTDs and Schemas that are made public by W3C. Being
the issuing authority this is less likely to be incomplete or outdated.
They also have the statistics needed to know which ones are the most
asked for and hence which one would be the most effective to cache data.
I'm sure SVG, or more recent XHTML versions would be useful additions
to the existing xhtml1-dtds, for example.
