Re: [xml] catalogs, include and import

[Michael Rothwell <rothwell holly-springs nc us>]

As it turns out, you're right about catalog support requiring 
/etc/xml/catalog to exist. On Windows, the path appears to be simply 
"etc\xml".

The strace output shows this (notice the lack of a leading "/" or "\" in 
the NtOpenFile call!)

When I make a `pwd`\etc\xml and put a catalog file in it, the test 
program works.

That doesn't seem like the "right" behavior. I wonder if "etc\xml" is 
hardcoded.

I'm ccing the list on this one.
