+/**
+ * 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.
