IIRC, this has to do with the > caching. Implement custom transformer if you want, it can have > parameters. The problem is we have written a "template-based" serializer. The pipeline generates the data, and the serializer uses the template and the date to produce the output. The template is unfortunately not in XML-Format, so it cannot be processed in the pipeline. Instead the template filename should be passed as parameter to the serializer. If caching is the only reason for not being able to allow pipeline-dependent parameters - in this case it would be simple to not use the caching (i.e. do not implementing the Cachable-Interface) for this special serializer and there should be no problem with caching. In the existing C2 architecture the lack of pipeline-dependent parameters is quite limiting. Now the only solution is to put the template parameter in the XML stream to "parameterize" the serializer (but this is mixing of content and formatting information) or to fix it in the serializer definition and duplicate the serializer for each different parameter which is even worse (and it would be not possible to get the parameter definition from a database or other source). Patching cocoon for our needs in this case is no option either, because this would change interfaces "in the heart" of the pipeline processing and we would not be able to upgrade to future cocoon-versions without problems. I think a lot of other serializers would benefit from pipeline-dependent parameters, too, i.e. the compressing factor/background color of the svg serializer or the doctype of the HTML serializer (just think of the problems of some Netcape 6 version with some special doctype definitions).
