Another alternative:
Output in base portlet package as abstract stubs or an
interface. Both SAX and Stream as child packages portlet.sax
and portlet.stream, respectively. Set up the default mode
using a properties file.
This will allow a more natural subclassing of output functions
which don't necessarily need to be based upon streams.
