I think this whole thread is slightly bogus. It should be obvious that
whatever is in the svn:author field has better be a unique identifier of
the person responsible for the commit, regardless of how it gets there.
Once that requirement is met, everything else is "simply" a matter of
getting the repository administrator to set up that identifier in such a
way that the tools user by the users of that repository can do something
useful with it.

I propose that this is /entirely/ in the domain of the organization that
is maintaining the Subversion installation. There is no standard way of
identifying all pertinent user information -- or rather, there are some
57 different standards. There's nothing stopping the repository
administrator from writing a pre-commit hook that adds tailored revprops
with identifiers that comply with all those 57 standards and any custom
ones, too. Asking Subversion to add reserved revprop names for all
possible (not even plausible) identification schemes would be a bit like
asking to add a different boolean property for every known character
encoding -- in other words, an explosion of reserved property names that
would, in general, give no benefit to the vast majority of users.

All that would happen is that different organizations would abuse those
property names in different, incompatible ways.
