As far as I know it's not that the xml:base is omitted, but that it is
not 'fixup'ed when including a file from the same directory. So one
solution might be to have a xml:base='<base-URI-of-this-file>' in
each include file.


BTW I know there have been some discussions about xml:base fixup
being required by the XInclude standard, but under Eclipse we use
Apache Xerces which has a feature to switch off 'fixup-base-uris'.
This allows us to use XInclude without going through updating each and
every Schema file. 
In order to use the same with xmllint we have patched libxml2 to
provide a --nofixup-base-uris option preventing xml:base fixup at all
(moreless the opposite of what Catherine wants), would there be any
interest in this patch?
