  12  * might check http://www.hansanderson.com/php/xml/ to see
  13  *
  14  * usage: $xml = xmlize($array);
  15  *
  16  * See the function traverse_xmlize() for information about the
  17  * structure of the array, it's much easier to explain by showing you.
  18  * Be aware that the array is somewhat tricky.  I use xmlize all the time,
  19  * but still need to use traverse_xmlize quite often to show me the structure!
