  <para>
   This is used to
   <link linkend="api.append">append</link> values to the templates by reference.
   If you append a variable by reference then change its
   value, the appended value sees the change as well. For
   <link linkend="advanced.features.objects">objects</link>,
   append_by_ref() also avoids an in-memory copy of the appended object.
   See the PHP manual on variable referencing for an in-depth
   explanation. If you pass the optional third parameter of true,
   the value will be merged with the current array instead of appended.
