The ResponseWriter is simple to write small renderers by hand, but it is
going to be painful in the complex cases. The standard JAXP interfaces
are needed for integration purposes, like rendering SVG graphics from
Batik, RDFa from Jena or Sesame, office XML documents and even render
components as JAXB-annotated beans. The ongoing HTML5 standard is also
much more XML-like.
