*Scoped Queries*

This has been discussed extensively in the past. Basically, the idea is
that the selector would be evaluated in the scope of the element, in a way
more compatible with how libraries like JQuery work. This slightly
different from the :scope pseudo-class proposal, see bug for details.
Note that what makes the ">strong, >em" selector (which apparently
some libraries support) hard to support spec-wise is that that is not
in fact valid CSS syntax. It's certainly possible to define behavior
for it, it's pretty clear to me how it's intended to work, but it
would mean specifying our own syntax.
It is clear how it is intended to work, but it is less powerful than a
:scope selector.
I suggest it is a low priority feature.
However if supporting commaseparated queries is critical for libraries
then I see no other choise. We'll one way or another have to specify
our own syntax, though it can be heavily based on the productions in
the Selector spec.

Libraries already parse selector queries anyway. And some of them add
non-standard selectors and presumeably will continue to do so. I don't
think it is an issue.
