Not a bad idea...

XInclude wouldn't come for free (the RDF/XML spec doesn't say that
RDF parsers must grok XInclude) but if we're interested in special
syntax for syntactic inclusion, I'd prefer XInclude syntax, which
is designed for exactly that purpose, rather than daml:imports,
which sorta looks like an RDF property but it's sorta unclear
how to specify that it acts like one.
