 	<em>This appendix is normative.</em>
 
 	Due to legacy Web-compat constraints,
 	user agents expecting to parse Web documents must support the following features:
 
-	* All [=pseudo-elements=] whose names begin with the string “-webkit-”
+	* '':-webkit-autofill'' must be treated as a [=legacy selector alias=] of '':autofill''.
+		<!-- expand this into a table or something if we add any more aliases -->
+
+	* All other [=pseudo-elements=] whose names begin with the string “-webkit-”
 		(matched <a>ASCII case-insensitively</a>)
 		and that are not functional notations
 		must be treated as valid at parse time.
