Subject: Fixed TransformerFacade doctype output for xalan::FormatterToXML *
 "xsl:output" was disregarded for xalan::FormatterToXML based output ** the
 setting contained within this tag have to be passed manually to the
 constructor... ** the xalan standard implementation includes special handling
 for this case ** sadly there was no alternative to adding special handling in
 InputXSLT as well, it is really quite ugly * added "dispatchTransformer"
 template member method to TransformerFacade ** calls xalan::FormatterToXML
 augmentation logic if needed, compiles template * this problem also exists
 for FunctionTransform output to xercesc DOM ** this patch doesn't aim to fix
 it in that case, it will have to be fixed separately
