Re: My comments on the X/Open PKI requirements document

Note: message carefully and intentionally cross posted.

fine.  you want another comment?  I think it's insane we have at least five
standards organizations or groups looking at vaguely the same problem.
(spki, pkix, x.509, aba, x/open.)  I just realized this a few days ago when
one or the other of the spki/pkix list had something on the x/open effort.

If the following statement is false then I apologize but....

if the x/open folks were doing things before spki and/or pkix came into
existance then I think they should have said something, rather loudly, on
the relevant mailing list.

if the x/open folks started things after spki and/or pkix then I assume that
either they think those groups are irrelevant or they have something more to
add to the effort.

Now I *know* I may have missed some message that went by recently to explain
why I've misunderstood what's happening.

Please, feel free to correct my statement.  I'm sure someone would have even
if I didn't give permission ;-)
