2.0  Reopening of Issue 5.26 (10 minutes)
Discussion of Jeremy's proposal re: B1 and B2
see message
http://lists.w3.org/Archives/Public/www-webont-wg/2003Mar/0197.html
and the messages linked from there.

jjc: objections summarised in
     http://lists.w3.org/Archives/Public/www-webont-wg/2003Mar/0192.html
pfps: nothing new to add
danc: is this aspect of 5.26 is represented in the test spec yet?
seanb: testcases for structure-sharing would be useful
jimh: two choices: 1. approve B1/B2, wait for proof later. disproof
      would mean design change
jimh: choice 2. incorrect implementations

STRAW POLL: adopting structure sharing seems to cause a risk that a
        proof be hard to find, not adopting structure sharing seems to
	have conformance risks
(poll yielded several for adopting structure sharing, one against)

pfps: tricky to fix document at later date (if disproof)
guus: this is design change of language - is it really something we
      can push in at a later point?
jimh: not hard to fix things (addition/removal of B1/B2) during LC
      period
jimh: pfps, could you get us a proof by end of LC?
pfps: yes, can spend the time
jjc: better not to go in before LC (and then add during LC)

ACTION: Patel-Schneider to work on proof for issue 5.26 B1/B2

RESOLVED to close issue 5.26, accepting all the points from the
        original document except B1,B2

        (Carroll objects, Connolly, Obrst and De Roo abstain)
