I would support the latter, as it is another step closer to Xanadu-style
hyperlinks.  As documented in "Literary Machines" and elsewhere, Xanadu
hyperlinks have a "type" endset as well as a "from" and a "to" endset for
just this reason (that is, allowing an infinitely extensible set of link
types).  They also have a "home" endset, representing the document in which
the link is contained, which is therefore not necessarily the same as the
document the link points from or to, a capability sadly missing from WWW.

I am continually fascinated how pioneering designs are recapitulated...
