Nothing special so far as the sitemap goes, I'd say, just include your transformer in the pipeline under the appropriate matcher. The "trick" is in the coding of your WFS transformer - by default have all the received events passed straight through to the registered consumer, until you receive a startElement for the wfs:GetFeature. At that point, start recording the subsequent events (i.e. the contents of the element) to a buffer or whatever, until there's an endElement for wfs:GetFeature. At that point you call your WebFeatureService with the recorded parameters then send the consumer the appropriate event stream for the results instead of the original GetFeature element, in this case the wfs:featureCollection. Nothing unusual there, many of the existing transformers work the same way; everything gets passed through until a specific namespace and/or element is encountered, at which point they start recording the stream for later processing. Some of them have a number of triggering elements, with a field to store the current state i.e. which of several buffers should currently be used for the recording.
