Looking at use cases for the "Identifier syntax" would allow me to catch
up. I have been looking for such (free interpretation please) 'URI
scheme' ideas but with little luck.

I liked the "additional benefit" your Internet-Draft. Some time ago, I
posted to some lists about the inability of one to bind URIs to prefixes
as 

<ns1:rootElem xmlns:ns1="http://www.myOrg.org/ns/2002/" 
  xmlns:ns1.1 = "ns1:foo1.xsd#" 
     xmlns:ns1.1.1 = "ns1.1:typeID">

Do you think that using a construct of qnameAsPrefix+'.'+URI_patch is a
good idea? This defers from your draft as it does not try to introduce a
new 'scheme indicator' although can also be done. But the juice of this
is that I tried to produce a valid syntax to "layer" namespace
declarations (that in turn could be used for ontologies stuff). I am
aware of no valid syntactical means that help in URI layer architecture.

Considering recent conversations around things like URI != vocabulary, I
find it weird that I saw none expressing the view that at least a *set*
of URIs can represent and encapsulate (as retrievable  URLs) anything,
including a vocabulary hierarchy in any form of Schemata.


Kindest regards,

Manos
