-<a>Live</a> vs <a>Snapshot</a> Selector Profiles</h3>
-
-	Selectors are used in many different contexts,
-	with wildly varying performance characteristics.
-	Some powerful selectors are unfortunately too slow
-	to realistically include in the more performance-sensitive contexts.
-	To accommodate this, two profiles of the Selectors spec are defined:
-
-	<dl>
-		<dt><dfn local-lt="live">live profile</dfn>
-		<dd>
-			The <a>live</a> profile is appropriate for use in any context,
-			including browser CSS selector matching, which is live.
-			It includes every selector defined in this document,
-			except for:
-
-			<ul>
-				<li>The '':has()'' pseudo-class
-			</ul>
-
-		<dt><dfn local-lt="snapshot">snapshot profile</dfn>
-		<dd>
-			The <a>snapshot</a> profile is appropriate for contexts which aren't extremely performance sensitive;
-			in particular, it's appropriate for contexts which evaluate selectors against a static document tree.
-			For example, the {{Element/querySelector()}} method defined in [[DOM]] should use the <a>snapshot</a> profile.
-			It includes all of the selectors defined in this document.
-	</dl>
-
-	CSS implementations conformant to Selectors Level 4 must use the <a>live</a> profile for CSS selection.
-	Implementations using the <a>live</a> profile must treat selectors that are not included in the profile
-	as unknown and invalid.
-
-	<p class='issue'>
-		The categorization of things into the “live” or snapshot profiles needs implementor review.
-		If some things currently not in the live profile can reasonably be done in CSS Selectors,
-		we should move them.
