I think  "entity::idref"  is a different type of thing to  
"namespace::name", and I'd prefer to see  "entity+idref", 
which I think was Martin's original delimiter.   

I think we can use "::" to mean a document-level namespace 
delimiter. In other words, FOO::BAR means that I have, 
notionally, imported an element set from somewhere and given 
it the prefix FOO for unique-izing names. The document has 
several namespaces, FOO is one of them.
 
The "+" is an inter-document namespace delimiter. So JANES+SUBS
would mean in the document with entity name JANES, the ID SUBS. 

If we make these type of conventions now (in particular the "::"
namespace::name delimiter) it will give people a lot to go with.  

I don't think we need the "+" form in XML because
	<link	  refid="xxx+zzz"  />
we can already do with
	<link   href="&xxx;#zzz" />

Nice.
