Yes, indeed, it's a very neat idea.

One drawback is that I don't think you can rely on all XSLT processors 
getting it right:

(a) In the XSLT 1.0 spec it's not unambiguously clear that 
unparsed-entity-uri() is expected to return the absolute URI, and I 
believe there are processors that return the system ID as it appears in 
the source

(b) XML parsers aren't always very good at reporting information about 
unparsed entities. For example in Saxon-CE we generally can't get this 
information from the native XML parser in the browser, and so 
unparsed-entity-uri() generally doesn't work.
