 * A note on how handlers create changes; this is done by assigning a new
 * value to the $token reference. These values can take a variety of forms and
 * are best described HTMLPurifier_Strategy_MakeWellFormed->processToken()
 * documentation.

 * @todo Allow injectors to request a re-run on their output. This
 *       would help if an operation is recursive.
