<br><font size=2 face="sans-serif">Hi Bill,</font>
<br>
<br><font size=2 face="sans-serif">I think your recommendation "</font><font size=2><tt>for
a re-look"</tt></font><font size=2 face="sans-serif"> of use scenarios
and requirements is good. But I would like to remind you all that the "Network
Scan Use Cases and Requirements" had passed PWG Last Call, contains
many use cases and design requirements for Scan Service and part of Resource
Service.</font>

<br>
<br><font size=2 face="sans-serif">IPP and PSI also had very good use cases
and design requirements developed before the specs were finalized. I think
these can be very good references for the start of your "rationale"
document for the MFD Overall Semantics. </font>

<br>
<br>
<br><font size=2><tt>This should deal with almost all of the issues brought
up in October. I have<br>
noted most of these changes (other than purely editorial) with highlighting.<br>
I have also added a few comments, which are actually questions to be<br>
addressed.<br>
</tt></font>
<br>
<br>
<br><font size=2><tt>For whatever reason, MS Word is really having problems
with this document,<br>
inconsistently updating figure and table references and locking up at least<br>
one a session. maybe my program is corrupted. Updating cross references<br>
manually is prone to error (and attention fatigue.) I am putting off putting<br>
in references until the text is basically stable (which will be soon I<br>
hope.)<br>
</tt></font>
<br>
<br>
<br><font size=2><tt>Note that it was agreed to put the "Rationale"
in a separate overall<br>
document. I will post a first cut (and sparse) draft of that tomorrow<br>
morning. I think it important that this be properly considered and "real",<br>
not just some words to nominally satisfy something in the PWG Process<br>
document. I really need help with this.<br>
</tt></font>
<br><font size=2><tt>1. What do we intend in the Service
Descriptions?<br>
</tt></font>
<br><font size=2><tt>2. Why are we doing this? That is, what
are the scenarios that show the<br>
need for the information in these documents? (This will imply a way in
which<br>
this information will be used.)<br>
</tt></font>
<br><font size=2><tt>3. What are the requirements that must
be addressed in the Service<br>
Descriptions (and associated documents)?<br>
</tt></font>
<br><font size=2><tt>I think that we all had some notion of these things
when we started,<br>
although they may not have been the same. It is unclear whether, as this<br>
activity has progressed, these ideas have solidified, become more consistent<br>
or perhaps have become confused in details and mechanics and have<br>
dissipated. This is a good opportunity for a re-look, with either resulting<br>
affirmation or modification.<br>
</tt></font>
