Why do you need to wrap the URI in any characters at all?  Why not just do:


I know there are two : characters in there, but you just have to specify 
that it is the last occurence of the : character delimits the local part 
from the namespace.

When namespace prefixes come into play they are just treated them as aliases 
of the URI they represent.

A bit like in C# (and presumably Java) you can specify:

    private Microsoft.Office.Interop.Word.Application  word = null;

and there's no ambiguity about which is the local part.

And you can set up an alias as:

    using Word = Microsoft.Office.Interop.Word;

and do:

    private Word.Application  word = null;

There's also the issue that there is an abundance of / characters in the 
original example name, which may conflict with XML parsing of elements such 
as <empty/>.  But I assume that would be a problem for the {uri}local type 
schemes also.  And it doesn't seem too difficult to come up with rules that 
would allow the meanings of the / characters to be disambiguated.  (e.g. If 
there is a : any / before the last : is part of the URI, not part of the XML
