	They are not "scheme dependent".  They are defined via application
conventions, presently for text/html documents, and should apply no matter
what scheme is used to retrieve such documents (i.e., not just http, although
HTTP/1.n has one of the clearest means of specifing the MIME type).  (An)
application convention(s) could, someday, be specified in relation to (a)
scheme(s).  Why impose a restriction against someday doing so for some URNs,
or for URNs that might return text/html documents such that the existing
conventions would apply?
