    Pokud chcete pouvat WDDX, budete muset nainstalovat expat knihovnu
    (kter je u Apache 1.3.7 a vych) a zkompilovat PHP s
    <option role="configure">--with-xml</option> a
    <option role="configure">--enable-wddx</option>.
   </para>
   <para>
    Pozn.: vechny funkce kter serializuj promnn pouvaj prvn element
    pole k rozhodnut jestli se toto pole serializuje do pole nebo struktury.
    Pokud m prvn element etzec jako index, serializuje se do struktury,
    jinak do pole.

    <example>
     <title>Serializace jedin hodnoty</title>
     <programlisting role="php">
&lt;?php
print wddx_serialize_value("PHP to WDDX packet example", "PHP packet");
