Updated schedule from liaison subcommittee

On today's liaison call the subcommittee came up with a new proposed 
schedule:

16th Feb: Assembly and Policy PR draft ready
23rd Feb: vote on Assembly/Policy PR

BPEL/Bindings/C/C++ to lag Assembly/Policy by two weeks.

This assumes that the upcoming assembly/poilcy f2f meeting will resolve 
all the major issues for assembly and policy. It also assumes that there 
won't be any changes to the assembly/policy specs that cause a big 
ripple effect on other SCA specs.

Given where we are wrt our issues and spec status, it seems reasonable 
to me.

Comments on the new schedule?
