I agree with that and indeed this works fine in RDF systems I have
used.  In Redland[1] I have a URI class that allows you to create
URIs from parts (relative to base URI for URIs that follow the
hierarchy style) but has no methods to sub-divide them.  

There might be a few methods required on an URI in an RDF system to
get the fragment (#foo) since I think that's outside the opaque part
or maybe the URI scheme (http: etc) but I've never needed them yet.

I feel it might be needed for serialisation of the RDF graph to
RDF/XML, but I haven't implemented that yet.
