"1.4 Namespace reads in part:

• • • • • 
          If an implementation is using the XML Encoding according to the OBIX Encodings specification document, the XML namespace URI (see XML-ns) that MUST be used is:

http://docs.oasis-open.org/obix/ns/201310

I read the use of the specified namespace as a normative requirement but when I attempt to ""dereference"" the namespace, I get a 404 message. (as of 5 February 2014)."
