[Team 6401]: composition approach in WS-E format

This is the concrete "composition" proposal version 0.7 in WS-Eventing
spec format based on the current Editor's copy.

This concrete proposal for the composition approach has progressed to
version 0.7, distributed to WG in last May
http://lists.w3.org/Archives/Public/public-ws-resource-access/2009May/01
70.html and been discussed within 6401 task force team.

The goal and scope of issue 6401 is to make WSDLs of WS-Eventing BP
complaint to support the event deliveries, i.e. raw and wrapped,
specified by WS-Eventing. And this proposal is a fulfillment of that
goal.

Thanks,
