Prior to yesterday's telecon the group had a consensus that they 
could live with the "allDisjoint" solution (essentially what Jos 
proposed a month or so back).  Dan's proposal had more support, but 
under the assumption it was technically feasible.  If the WG 
indicates that they agree with Peter and/or prefer this decision, I 
will be willing to revisit our decision.  If not, then we can go to 
LC without the semantics document, and resolve this and release that 
document in LC form as soon thereafter as we can
