And what about the root tag? You want to keep the pipeline well-formed.Well Cocoon does not garantuee this. It is a common mistake (did itmyself quite often) to forget in a XSLT stylesheet to always set a roottag (<template match="/"><myroot>...).
That's true ...but still you want or even need the pipelines to be well-formed ;)
Cocoon is *streaming* the XML through the pipelines. That's what you would expect from a today's XML pipeline architecture ...which is also the reason why you cannot react on XML values inside the stream from the sitemap level without buffering the whole process.I was thinking out-of-the-box about functional/conceptual requirements. Your reply is about technical implemention/performance issues. Of course these are sometimes hard to separate because you cannot build something which is impossible (my computer still makes no breakfast). But really, if you take a step back it is hard to explain to new XML pipeline userswhy they can select on a request parameter but not on a XML field.
It might be something we have to explain to a user but we have a *concept* of streaming pipelines so... I am not sure if this is just an implementation detail ...but anyway cheers -- Torsten
