In reply to:

I'm having a problem with declarations/xml.decl not being found. I can't find that anywhere on my system - do you know what package owns it?

On my Debian system, it belongs to the "sgml-data" package (on which OpenJade depends):

sgml-data: /usr/lib/sgml/declaration/xml.decl

I had hoped to find it available on the W3C Web site, but they seem to want to quietly forget XML's origins to concentrate on their own XSchema stuff. Anyway, you can get a copy from OASIS. Does that help?
