                        XMLTypeCreator.java
  Log:
  Updated DTD to use "info" element in preference to "component" element as
  the work "component" appears in the general container descriptor and is a
  potential source of consusion.  Secondly, the "component" element at a type
  level is not defining a component but is instead defining information about the
  type.  Changes are bakward compatible and do not require a version change.
