-<para>The properties that apply to the containing
-block of a level-2 section, and therefore apply to
-the whole section.  This includes <tag>sect2</tag>
-elements and <tag>section</tag> elements at level 2.
-</para>
-
-<para>For example, you could start each level-2 section on
-a new page by using:</para>
-<programlisting>&lt;xsl:attribute-set name="section.level2.properties"&gt;
-  &lt;xsl:attribute name="break-before"&gt;page&lt;/xsl:attribute&gt;
