Re: fn:document-uri in Saxon and XMLSpy

document-uri() is defined to return a URI and the URI corresponding to a
windows file path like
c:\a\b\c.txt
is
file:///c:/a/b/c.txt

URI relative references and things like .. going up a level are _only_
defined for / separated URIs. 

If a system treats

c:\a\b\c.txt

That as a URI then that is legal (athough it is using an unregisted URI
scheme of c: but if that is your base a relative URI of d.txt would
not reference
c:\a\b\d.txt
as URI relative references are defined in terms of stripping back to the
last / character and there are no / characters here.


Some browsers in the top level user-input box accept windows paths and
change them internally to URI but no programming APi should do that
automatically.

So xml spy is buggy in returning a "uri" using \ characters, but you
could work around teh bug by using 
tokenize(document-uri(.), "[\\/]")
which will split on both \ or / but you should report the bug to  xml
spy's maintainers.
