This is an excellent proposal.

One way to use something like this in RDF is to elevate urispace to 
the status of a uri scheme--

<Description about="urispace:http://akamai.com/NoGoUrispace.xml" 

"resources in the space denoted by the urispace specified by 
NoGoUrispace.xml exclude robots"

A urispace protocol handler could then evaluate the resource at the 
sub-uri and generate verbose RDF if appropriate.
