No, it isn't possible to use params in xsl:include or
xsl:import href attributes.  The solution is to
use XML catalog files to remap the URI to different
actual file paths.  You can create different catalog files
for different purposes, and your command line can select the
appropriate catalog file.

There is help for setting up catalog files in Dave Pawson's FAQ:

http://www.dpawson.co.uk/docbook/catalogs.html

but I think that FAQ is off the air at the moment?
Has it been moved, or will it be coming back?
