Ooops.  I was writing this right before I had to run to a meeting and hit
send without finishing my thoughts.  I had left Austin's "(2.1 at least)"
part in the quote because he is correct that this is a new requirement of
2.2.

My intent was not to be critical of Austin's comments but to add more
details to it.  I appologize if my incomplete thought might have left any
other impression.

For the record, I agree with both of Austins' posts in this thread so far.

Sincerely,
