A URI scheme or a Web authority may define that two URIs differing only 
in case are equivalent. However, generic RDF processors will not 
recognize this; you'd have to state e.g.

     <mailto:foo@example.org> owl:sameAs <mailto:foo@Example.org>

Of course, you can teach any specific RDF processor that specific URI 
schemes are case-insensitive, but you cannot assume this to be known by 

RDF does define that any two URIs differing only in case are to be 
treated differently *in the general case*-- a processor cannot assume 
them to be equivalent.

Clearer what I meant?  :-)
