This modification will allow instances like this:
-<programlisting language="rng"><![CDATA[<author>
+<programlisting><![CDATA[<author>
<personname>Babe Ruth</personname>
<born>02/06/1895</born>
<died>08/16/1948</died>
but because we only modified the content model for authors
who are human, it won't allow an instance like this, which
uses <varname>db.org.author.contentmodel</varname>:
-<programlisting language="rng"><![CDATA[<!-- INVALID -->
+<programlisting><![CDATA[<!-- INVALID -->
