 	Three new properties are introduced to allow column breaks to be
 	described in the same properties as page breaks: 'break-before',
-	'break-after', and 'break-inside'. These properties take the same
-	values as 'page-break-before', 'page-break-after', and
-	'page-break-inside'  [[!CSS21]]. In addition, some new keyword values
-	are added.

-	These properties describe page/column break behavior before/after/inside the generated box. These values are normatively defined in [[!CSS21]]:
-
-	<dl dfn-type=value dfn-for="break-before, break-after, break-inside">
-		<dt><dfn>auto</dfn>
-		<dd>
-			Neither force nor forbid a page/column break before (after, inside) the generated box.
-
-		<dt><dfn>always</dfn>
-		<dd>
-			Always force a page break before (after) the generated box.
-
-		<dt><dfn>avoid</dfn>
-		<dd>
-			Avoid a page/column break before (after, inside) the generated box.
-
-		<dt><dfn for="break-before, break-after">left</dfn>
-		<dd>
-			Force one or two page breaks before (after) the generated box so that the next page is formatted as a left page.
-
-		<dt><dfn for="break-before, break-after">right</dfn>
-		<dd>
-			Force one or two page breaks before (after) the generated box so that the next page is formatted as a right page.
-	</dl>
-
-	This specification adds the following new values:
-
-	<dl dfn-type=value dfn-for="break-before, break-after, break-inside">
-		<dt><dfn for="break-before, break-after">page</dfn>
-		<dd>
-			Always force a page break before (after) the generated box.
-
-		<dt><dfn for="break-before, break-after">column</dfn>
-		<dd>
-			Always force a column break before (after) the generated box.
-
-		<dt><dfn>avoid-page</dfn>
-		<dd>
-			Avoid a page break before (after, inside) the generated box.
-
-		<dt><dfn>avoid-column</dfn>
-		<dd>
-			Avoid a column break before (after, inside) the generated box.
-	</dl>
-
-	When a page or column break splits a box, the box's margins,
-	borders, and padding have no visual effect where the split occurs.
-	However, the margin immediately after a forced page/column break will
-	be preserved. A forced page/column break is a break that does not occur
-	naturally.
-
-	Note: In the future, new properties may describe alternate
-	ways to handle margins, borders and padding around page/column breaks.
-
-	<div class="example">
-		In this example, forced column breaks appear before <code>h2</code>
-		elements and after <code>img</code> elements:
-
-		<pre>
-		.multicol { column-width: 8em }
-		.multicol h2 { break-before: column; margin-top: 2em }
-		.multicol img { break-after: column }
-		</pre>
-
-		The top margin of <code>h2</code> elements will be preserved since the column break is forced.
-	</div>
-
-	<div class="example">
-		In this example, the formatter will try avoid column breaks inside <code>p</code> elements:
-
-		<pre>
-		p { break-inside: avoid-column }
-		</pre>
-	</div>
-
-
+	'break-before', 'break-after', and 'break-inside'
+	are defined in [[!CSS3-BREAK]].
