As has been pointed out, you can't. One thing you can do is use a
framework that allows relative paths to be resolved for your stylesheets
independently of the XSLT in use (IOW, one that includes URI resolvers
that do the dirty work for you). If you're in a position to do so you
might want to look at the Apache Cocoon project for such capabilities.
It would also give you the capability to dynamically generate a top
level XSLT that includes the lower level XSLTs; you'd generate the XSLT
and the relevant include paths at run time and then execute it...
