Yes, we need pipeline-depended parameters for serializers! See thread http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=101560153713851&w=2
We developed a very special serializer which makes really no sense without serializer parameters; and using an additional parametrizable transformer would be an ugly hack.
