Problem with xsltproc on Windows

Hi!  I've been trying to do some Docbook processing with xsltproc on
Windows, and I am having some difficulties.  I'm not sure if this is a
libxml issue, libxslt issue, or both so I have emailed both lists:

Using the Windows binaries for libxml, libxslt and xsltproc.exe from
http://www.zlatkovic.com/libxml.en.html I get the following results
when trying to use xsltproc with a catalog file (I'm using a CMake
script to set the environment variables and actually launch the
command).  This setup works (obviously with different paths) on all
non-Windows systems I've tried it on - is there something special I
need to do for catalog files on Windows?

Any help appreciated - thanks!  (Let me know if anything besides what
is below is needed or would be helpful.)
