Cool! Some quick feedback:

* you should explicitly accommodate target attributes (i.e., extension fields)
* 'rev' was only included in 5988 for backwards compatibility with some fairly esoteric use cases; don't think it's necessary or good here.
* you need to specify how to determine the context of the link (using RFC5988 terminology). 

Cheers,

While that makes sense from the standpoint of ENUM, if this mechanism is truly generic to *all* URIs, it seems to me that it'd be much more sensible to use the typing system already in place for URIs -- link relations <http://tools.ietf.org/html/rfc5988>.
