optional stuff (was Re: URL-level trust (was: Re: XKMS))

Changing the subject line's becoming a habit, but I want to 
separate threads. Mike's text (below) suggests defining an
element that allows the client to identify itself to the 
responder. Now, that's fine (and can be discussed on the
other thread), but I can't see us insisting that that field 
is always filled-in, - if we added it, it'd most likely 
be "optional".

So, my question is about optional fields - what should our
attitude be to these? IMO, the presence of optional fields
in other specifications has caused problems (less interop, 
more complex specification), but has also provided a way
to reach concensus (or maybe just push things under a 
carpet).

I'd love to have a rule of thumb, specific to our situation, 
that we can apply as folks suggest their favorite feature be 
added as optional (as we all will:-).

Anyone care to suggest such a "rule"?

Stephen.
