I found that default cygwin installation of docbook was pointing at
the wrong external address.
Here is the content of my /etc/xml/catalog file. The commented out
lines are what came during the package install, the lines below them
are mine. That seems to redirect validator from the root written in
our manual (docbook.org) to /usr/share/xml/docbook...
The root that comes with the package is oasis-open.org - it doesn't
match what we have in the manual, and the validator complains.
Ideally, cygwin package should be updated, but who knows.
