<para>The properties that apply to the containing
block of a level-4 section, and therefore apply to
the whole section.  This includes <tag>sect4</tag>
elements and <tag>section</tag> elements at level 4.
</para>

<para>For example, you could start each level-4 section on
a new page by using:</para>
<programlisting>&lt;xsl:attribute-set name="section.level4.properties"&gt;
  &lt;xsl:attribute name="break-before"&gt;page&lt;/xsl:attribute&gt;
&lt;/xsl:attribute-set&gt;
</programlisting>

<para>This attribute set inherits attributes from the
general <tag>section.properties</tag> attribute set.
</para>
