RE: Lee's feature proposal

I am reasonable comfortable with the list except that explanation of not including "negation" does not make sense to me.

I am surprised.

It comes out well on the WBS.

It has user exposure via OPTIONAL!BOUND and that experience is that the current way is hard to use. 

This is a feature I have said I will champion as noted on the wiki (as per below).

We are deciding a feature list, not an implementation list. It may well be a subquery, so I suggest including it in subqueries, but not putting on either list based in part on that does not make sense to me.

I am surprised at prioritisation.  The survey captures WG members sense of priorities by the ranking.  See also below.

In my opinion, one of the important aspects of a working group is that the group as a whole devotes time to the consideration of a feature, review of material and preparation of the final concrete deliverables.  Having someone to put energy into a feature is only one side of the equation.

There was no strawpoll the second time.

Other people said they would champion other features.

(This is not directed at Bijan whose energy in this WG I appreciate)
