I just tried it with xsltproc from libxml 2.4.30 and libxslt
1.0.23, and it seems to support multiple catalogs now.
It used to be true that only one catalog file was supported.
Apparently this has been fixed in xsltproc, so you can use
multiple catalog files. I don't know
what version it started working in.
There is no mention in the ChangeLog that I can see.
You must separate catalog files with
spaces in the environment variable. Neither colon nor
semicolon worked as a separator for me.
