  <para>
   Set a handler to be called when leaving the scope of a namespace
   declaration. This will be called, for each namespace declaration, after
   the handler for the end tag of the element in which the namespace was
   declared.

       <parameter>handler</parameter> is a string containing the name of a
       function that must exist when <function>xml_parse</function> is called
       for <parameter>parser</parameter>.
      </para>
      <para>
       The function named by <parameter>handler</parameter> must accept
       two parameters, and should return an integer value. If the
       value returned from the handler is &false; (which it will be if no
       value is returned), the XML parser will stop parsing and
       <function>xml_get_error_code</function> will return
       <constant>XML_ERROR_EXTERNAL_ENTITY_HANDLING</constant>.
