Were it to do so (provide general information), I'd hope that there would be some intervening redirection so that there is no confusion that what is returned is a awww:representation of the referent of:

   http://xri.org/xri:/xri.boeing.com/@boeing*jbradley/+home/+phone

Hmmm...which, intentionally would be what?

 - Boeings record of jbradleys home phone number?
 - Boeings metadata about Boeings record of jbradleys home phone number?

Something else entirely?

I'm not sure if I am supposed to be able to tell.

Regards

Stuart
