 * This is a stable release, 1.0.  I don't foresee any changes, but you

 * usage: $xml = xmlize($array);
 *
 * See the function traverse_xmlize() for information about the
 * structure of the array, it's much easier to explain by showing you.
 * Be aware that the array is somewhat tricky.  I use xmlize all the time,
 * but still need to use traverse_xmlize quite often to show me the structure!
