Hi Norman,

You certainly can use the pattern <http://example.com/about/alice#alice>, and here the per-identifier document <http://example.com/about/alice> is an IR and the identifiers <http://example.com/about/alice#alice> or <http://example.com/about/alice#i> are not.

If their "hash-URI" scheme is intended to cover your scheme, too, then the cooluris document may need a little clarification.

Hmm, I don't see a distinction between the patterns to be honest, 
Richard / Leo can verify if they are distinct, personally think it could 
be better clarified to use a few different uris, some where it's one 
resource per doc, some with more than one.

   <http://example.com/alice#me>
   <http://example.com/about#bob>
   <http://example.com/about#frank>

for instance, or something even clearer.

Best,

Nathan
