It doesn't preclude anything, nor does it provide the author with any
guidance for consistency (i.e. the field names do not make sense).  Further,
there is a significant semantic difference between the OWNS relationship
(described in Tim's reply) and the MADE relationship.

First of all, comments are not hidden -- they can be seen in the source.
Second, it is important to provide a means of indirection AND stating the
expected use up-front so that future tool-writers can avoid assuming that
it is an e-mail address and, if necessary, take advantage of the alias
feature.  Third, of course it's foolish -- that is the nature of a kludge.

It exists as an HTTP header but there is no defined means for providing
that information to the server for HTML files.  Thus, some form of
HTML element is needed.
