-Scoped Descendant Combinator</h3>
-
-	The <dfn export>scoped descendant combinator</dfn>
-	describes a descendant relationship between two elements.
-	A selector of the form ''A >> B'' represents
-	an element <code>B</code> that is an arbitrary descendant
-	of some ancestor element <code>A</code>.
-
-	This combinator differs from the [=descendant combinator=]
-	in that it applies [=weak scoping proximity=]
-	to the relationship between <css>A</css> and <css>B</css>.
-	It does not change the '':scope'' element.
-
-	ISSUE: Should the [=scoped descendant combinator=]
-	use strong or weak scoping proximity?
-	Should it even exist?
-	It's defined here to work the way many people expected
-	the regular [=descendant combinator=] to work...
-
-	<div class="example">
-		This means that style rules using the [=scoped descendant combinator=]
-		are sorted by specificity just like the regular [=descendant combinator=],
-		except that when their specificities are equal
-		the more tightly-scoped declaration wins.
-
-		In this example
-		the <code>&lt;a></code> element's color will be determined
-		by the nearest ancestor with either
-		a ''light-scheme'' or ''dark-scheme'' class.
-		(If the descendant selector had been used,
-		its color would always be ''plum'',
-		because it is later in the source order.)
-
-		<pre>
-			.light-scheme >> a { color: darkmagenta; }
-			.dark-scheme >> a { color: plum; }
-		</pre>
-
-		However if the <code>&lt;a></code> element has a ''light-scheme''
-		ancestor and is focused,
-		its color will be ''teal''
-		even if it has a nearer ''dark-scheme'' ancestor,
-		because there is no equivalent ''dark-scheme'' rule.
-
-		<pre>
-			.light-scheme >> a:focus { color: teal; }
-		</pre>
-	</div>
