  <para>
   Sets the unparsed entity declaration handler function for the XML parser
   <parameter>parser</parameter>.
  </para>
  <para>
   The <parameter>handler</parameter> will be called if the XML parser
   encounters an external entity declaration with an NDATA declaration, like
   the following:
   <programlisting role="xml">
<![CDATA[
<!ENTITY <parameter>name</parameter> {<parameter>publicId</parameter> | <parameter>systemId</parameter>}
        NDATA <parameter>notationName</parameter>
]]>
   </programlisting>
  </para>
  <para>
   See <link xlink:href="&url.rec-xml;#sec-external-ent">section 4.2.2 of
   the XML 1.0 spec</link> for the definition of notation declared
   external entities.
