-	This section describes how to <dfn>consume a unicode-range token</dfn>.
-	It returns a <<unicode-range-token>>.
-
-	Note: This algorithm assumes that the initial "u+" has been consumed,
-	and the next <a>code point</a> verified to be a <a>hex digit</a> or a "?".
-
-	Execute the following steps in order:
-
-	<ol>
-		<li>
-			Consume as many <a>hex digits</a> as possible, but no more than 6.
-			If less than 6 <a>hex digits</a> were consumed,
-			consume as many U+003F QUESTION MARK (?) <a>code points</a> as possible,
-			but no more than enough to make the total of <a>hex digits</a> and U+003F QUESTION MARK (?) <a>code points</a> equal to 6.
-
-			If any U+003F QUESTION MARK (?) <a>code points</a> were consumed,
-			then:
-
-			<ol>
-				<li>
-					Interpret the consumed <a>code points</a> as a hexadecimal number,
-					with the U+003F QUESTION MARK (?) <a>code points</a> replaced by U+0030 DIGIT ZERO (0) <a>code points</a>.
-					This is the <a>start of the range</a>.
-
-				<li>
-					Interpret the consumed <a>code points</a> as a hexadecimal number again,
-					with the U+003F QUESTION MARK (?) <a>code point</a> replaced by U+0046 LATIN CAPITAL LETTER F (F) <a>code points</a>.
-					This is the <a>end of the range</a>.
-
-				<li>
-					Return a new <<unicode-range-token>> with the above start and end.
-			</ol>
-
-			Otherwise,
-			interpret the digits as a hexadecimal number.
-			This is the <a>start of the range</a>.
-
-		<li>
-			If the <a title="next input code point">next 2 input code point</a> are
-			U+002D HYPHEN-MINUS (-) followed by a <a>hex digit</a>,
-			then:
-
-			<ol>
-				<li>Consume the <a>next input code point</a>.
-
-				<li>
-					Consume as many <a>hex digits</a> as possible, but no more than 6.
-					Interpret the digits as a hexadecimal number.
-					This is the <a>end of the range</a>.
-			</ol>
-
-		<li>
-			Otherwise, the <a>end of the range</a> is the <a>start of the range</a>.
-
