  47:  * This extends XMLWriter to create a class which defaults to writing
  48:  * XHTML text, preferring the US-ASCII encoding.  It adds no unique
  49:  * functionality, only changing the defaults slightly to simplify writing
  50:  * XHTML processing components by providing a bean class whose properties
  51:  * have more convenient defaults.  An artifact of using the US-ASCII
  52:  * encoding is that no XML declaration is written, so that HTML tools
  53:  * that can't accept them will not become confused.  Components can treat
  54:  * the output as UTF-8, ISO-8859-1, or US-ASCII without incurring any
  55:  * data loss.
