    * Attribute notes:

    * - each token in the date format is automatically replaced

    *   regarded as CDATA by the internal parser. For a list of
    *   supported date tokens, see the $tokensIndex property of
    *   the date element.
    *
    * - WARNING: due to a bug in PHP5 with the strtotime function
    *   (see http://bugs.php.net/bug.php?id=28209), the [now]
    *   directive will not include the current time, e.g. now will
    *   return a date like 12.05.2004 00:00:00. I recommend using
    *   timestamps directly when possible.
    *
    * - the returnformat attribute can be used to select the kind
    *   of value the date element will return. Possible values are 
    *   [isodate], [timestamp]. Default: [isodate]
