First of all, let me welcome you and PenOp to the W3C.  I hope you will be
able to join us at our Advisory Committee meeting in Toronto on May 10 &
11.  See


for details of the meeting and a link to the registration.

I imagine your new membership at this time is not entirely coincidental.  I
expect you are aware that we have just run a workshop on digital signatures
in XML.  There is a rather active mailing list that has developed as a
result of the meeting.  You can examine the archive at


In case you haven't heard, your system has been the subject of considerable
discussion.  Much of that discussion, in my opinion, is based on
considerable ignorance and speculation of just what your system does.

Unfortunately, it lacks sufficient detail for me to understand just how the
document hash and the act of signing are tied together inextricably.

We are in the process of trying to develop a specification for representing
as large a variety of digital signature methodologies as possible.  I hope
you will be able to review the mailing list archive and get a flavor of the
kinds of questions floating around.

I look forward to your active participation in the proposed working group
that ensues from this workshop.
