Subject: RE: [dita] processing-role: open items


Robert,

Thanks for this summary.

I believe we'll have agreement on most of what you say here,
but there are some subtleties that still need to be discussed,
and unfortunately I have to miss today's TC telcon, so I'd
ask that the TC make no final decision on this topic just yet.

We (Jeff, Dave, and I) plan to send email in response to further
the discussion as soon as we can.
