/**

 * This extends XMLWriter to create a class which defaults to writing

 * XHTML text, preferring the US-ASCII encoding.  It adds no unique

 * functionality, only changing the defaults slightly to simplify writing

 * XHTML processing components by providing a bean class whose properties

 * have more convenient defaults.  An artifact of using the US-ASCII

 * encoding is that no XML declaration is written, so that HTML tools

 * that can't accept them will not become confused.  Components can treat

 * the output as UTF-8, ISO-8859-1, or US-ASCII without incurring any

 * data loss.
