that's the semantic web world view, where URIs are completely opaque,  
always supposed to be http:, and to learn anything about them, a  
description must be found and used. on the plain web, URI schemes  
carry semantics, so that a client needs no additional information  
about tel: to be able to use these URIs. of course, the semantic web  
methods of describing something are far richer, but that should not  
imply that all URI semantics are or should be deferred to semantic web
