I noted that in the minutes there didn't seem to be much beyond the
name and a quick mention of the larger logical proposal... Was there
any more?  The reason I ask is that I think if affects the
conversation a little.  The above example looks mostly like the stuff
we are discussing for Selectors 4 and the point of asking for
consideration was the long view in which logicals would want to have
complex selectors - which I think frames the conversation better...
Just curious.

I'm aware of the history and the cases for the existing proposals.  At
one point, I think they made more sense because of what it was trying
to cover.  Still, I kind of disagree that

    ol li:any-of(aside li)

    or

    ol li:all-of(aside li)

    or

    ol li:one-of(aside li)

(or whatever we'd like to call logical stuff I described) is
inherently significantly less grokable somehow than :matches.  I'm a
lot more interested in rich set capability than names in the end - but
I do feel like there is a case to be made for those using a consistent
logical/set sort of language..

Is that different from in my proposal?  Explain where - I think I
might be misunderstanding something...
