In CSS, .foo .bar means any element with class bar contained anywhere within any element with class bar, that itself can be anywhere in the document and .foo > .bar means any element with class bar that is a direct child of any element with class foo, that itself can be anywhere in the document.
That is, given:
[:div.a
[:div
[:div.b "X"]]
[:div.b "Y"]].a .b would match [:div.b "X"] and [:div.b "Y"]
.a > .b would only match [:div.b "Y"]
Currently, sel only supports .foo .bar and not .foo > .bar. Support for direct-descendant selectors should be added.
Support can be manually obtained through the use of view, sel-* and the predicate functions, but support should be added to sel for convenience.
