 I freely admit that I was working towards a formal perspective, but I
don't see anything wrong with that, and furthermore the account I've sent
out so far is only pre-theoretic.

Where schema says the range is    http://schema.org/URL or
http://schema.org/Organization (as with http://schema.org/branchOf), should
we need to determine whether a textual string is a URI or a URL?

I ask because the DL literature did not manifest in a vacuum, and because
my RDF library has Literals and URI References.
