Re: [wsbpel] issue 168

[Diane Jordan <drj@us.ibm.com>]

You are right - thanks for catching
this. 
I have limited ability to edit in the
ballot menus (during opening and especially once the ballot is opened).
  I ask that everyone use the link to the email from Maciej to fully
understand option 2. 

I'd like to remind eveyone to vote for
this issue resolution and the other one up for a vote - issue 87.1.  These
are normative decisions - we need your participation to obtain a quorum.
  If you do not wish to make a choice, please vote and select abstain.
 Participation in ballots may be counted as a requirement for maintaining
voting rights - we have not done this in the past as we've not had difficulty
in getting a quorum on web ballots.   The ballots are at:

Diane,

Words like <receive> and <pick> have been dropped from
the option 2 description (probably through HTML editing?).
