The I18N WG discussed Namespaces in XML at its recent meetings:
   http://lists.w3.org/Archives/Member/w3c-i18n-wg/2002May/0062
   http://lists.w3.org/Archives/Member/w3c-i18n-wg/2002May/0078

Our conclusions are given below.  We would welcome a discussion of these
important matters.


DECIDED: Namespace URIs should allow the same range of characters as XML
System Identifiers.

Section
   1. Motivation and Summary
   http://www.w3.org/TR/xml-names11/#sec-intro
includes the following text:
   [Definition: URI references which identify namespaces are considered
   identical when they are exactly the same character-for-character.] Note
   that URI references which are not identical in this sense may in fact be
   functionally equivalent. Examples include URI references which differ
   only in case, or which are in external entities which have different
   effective base URIs.

DECIDED: It is unclear what is meant by "functionally equivalent" within
the context of the Namespaces specification.

DECIDED: The "character-for-character" comparison should be specified as
being case sensitive, eg:
-  "a" is not the same as "A"
-  "http" is not the same as "HTTP"

DECIDED: The Namespaces specification should make clear whether:
-  "%6A" is the same as "j"

DECIDED: The Namespaces specification should make clear whether:
-  "%6A" is the same as "%6a"
