FW: Agenda for XML Core WG telcon of 2005 April 6 -- Binary XML

>ACTION to Lew:  Review the documents and report to
>the WG by the end of March.

My apologies to the group for not getting to this sooner.  The customers
keep getting in the way.  I will plan to be on the call Wednesday.  Here are
my initial comments:

At the 50K foot level, this is one of the most significant extensions to XML
I think we have seen in some time.   My congratulations to the authors in
putting together a well thought-out and in-depth Use Case document and
implementation plan.   Although it is not clear as to how the various Use
case scenarios map to the Binary Characterization Properties that are
recommended.  E.g, a significant increase in performance with binary encoded
XML is being touted in the press.  I don't see that as primary objective.  A
summary matrix (BCP, must haves, nice to have, etc.) with weighting and
priorities would go a long way toward this end. 

The primary concern for out group will be the comprehensive set of
recommended Binary Characterization Properties and how they propose to
extend XML and existing processors as we know and love them.  There are
several much needed extensions including (compression, binary file
embedding, and multimedia content management).  However, several of the
proposed extensions that will impact us and should be assessed are:
  - Alternative Serialization its impact on the info set.
  - Alternative Content type management and dependencies.
  - XML processors and Stack Integration
  - end-to-end processing model
  - Deltas vs Fragments
  - Adhoc Schema processing and data typing
  - Binary vs Text processing and encoded header fields

Although BCP is a very comprehensive recommendation I see a lot of work on
the part of the core group in accommodating it in terms of sorting the
dependencies of the BCPs, how they play with the info set, and how to
characterize/implement support in existing XML processors.
