Hi,

  so I understand now that RDF people hijacked the XML namespace idea.
  There is currently no defined way to arrive from

<x xmlns:edi='http://ecommerce.example.org/schema'>
  <!-- the "edi" prefix is bound to http://ecommerce.example.org/schema
       for the "x" element and contents -->
</x>

  to a URI for "x". Options are:

- The RDF/XML community default (just appendd)
  http://ecommerce.example.org/schemax
  
-  The  RDF/XML  community default for namespaces that have no "#" or "/" at end
   http://ecommerce.example.org/schema#x

- The third option
   http://ecommerce.example.org/schema/x

- There are of course further options..


Can  we  make  the  semantic  web  a  better  place  by  releasing  a small note
(preferably from W3C) that says:

"To  get  a URI from an XML qname within an XML namespace, the last character of
the  namespace  URI  is  relevant. If it ends with a "#" or "/", the full URI is
namespace + qname. If not, the full URI is namespace + "#" + qname."

Something like this would ensure that all semantic web people use the same URIs,
e.g. for XML datatypes. And all other kind of XML data.

Kind Regards,
Max
