This section has already been copied to Selectors 4 (and has been
for awhile, actually), so should be removed here and replaced with
references to Selectors 4.

If there's anything that needs to be fixed in Selectors 4 for this
to be viable, then let us know and we'll fix it. :)

Tab just updated the grammar productions in Selectors 4 and defined
some terms, so this section shouldn't need to define anything, just
reference Selectors 4.

http://www.w3.org/TR/selectors-api2/#processing-selectors
We also added the algorithm for absolutizing a relative selector to
the Selectors 4 spec, so you can reference "scope-relative selectors",
as defined here:
http://dev.w3.org/csswg/selectors4/#scoping
Please let us know if there are any errors.
We'll try to publish a new WD soon with the updated definitions.
So, the new WD has been published:
http://www.w3.org/TR/selectors4/#scoping
However, in response to some Shadow DOM stuff [1] we've had to split
out the relative selectors section some more.
http://dev.w3.org/csswg/selectors4/#relative
While doing that, we noticed a problem with the absolutizing algorithm
in Selectors API2: if you explicitly pass in an empty reference element
set, document.find() searches the whole document. It should instead
return nothing.
Example:
document.find('img', [list-of-links]) /* find all images inside links */
Suppose the dynamically-generated [list-of-links] happens to be empty.
It returns all the images in the document, a very unexpected result.
We suggest that Selectors API 2 be updated to say that if a reference
element set is not given, the selector is assumed to be absolute (and
is parsed and interpreted accordingly) instead of relative.
Relevant terms in Selectors 4:
relative selector, defined in #relative
reference element set, used in #relative and #the-scope-pseudo
(We removed "contextual" because it seemed excessively verbose.)
