[occi-wg] Categorization via link relations

I really like the protocol, you've done a great job I have a question: Why is Category given a unique header, and not simply treated as another type of link relation for a resource? i.e. Category: compute; scheme="http://purl.org/occi/kind/"; label="Compute Resource" .. could that actually be written as: Link: <http://occi.org/kinds/compute>; rel=<http://purl.org/occi/kind>; title="Compute Resource" Cheers, Mike
