OASIS namespace documents for URN namespaces

Some OASIS TC's use an HTTP URI when they define an XML 
Namespace.  Some TC's have started using RDDL as a namespace document 
when these namespace URI's are dereferenced using HTTP GET.

Other OASIS TC's use URN's to identify their XML Namespace.

I suggest that OASIS provide a mechanism to resolve a namespace 
document (RDDL or other) using HTTP and passing in the namespace URN 
in a query parameter.

For example,

http://www.oasis-open.org/namespace?ns=urn:oasis:names:tc:emergency:EDXL:DE:1.0

would return a RDDL document associated with the EDXL-DE namespace.
