  <para>
   Disable/enable the ability to load external entities.
   Note that disabling the loading of external entities may cause general issues
   with loading XML documents. However, as of libxml 2.9.0 entity substitution
   is disabled by default, so there is no need to disable the loading of external
   entities,
   unless there is the need to resolve internal entity references with <constant>LIBXML_NOENT</constant>.
   Generally, it is preferable to use <function>libxml_set_external_entity_loader</function>
   to suppress loading of external entities.
