I think there is a solution that can avoid us messing with the output strategy. Take the feature collections and wrap them in a collection that will count and generate the bounds as the encoder streams through it (so you'll have to wrap both the collection and the feature iterator). Then let the encoder write out the xml, but instead of writing it out to the output stream, write it out to a temporary file. Then extract the count and bounds and apply an xslt transformation that will just add the count attribute and the collection bounds element to the result, this time piping the xslt transformation out to the output stream. The transformation should be really easy to write, as it goes to copy all elements, and should be fast, as the only non copy part is targeted to very specific elements (that you'll refer to by absolute xpath). If the admin chose the full buffering output strategy the net result wil be to write the xml on disk twice, but imho, such admin does not care about performance much anyways, so no big deal imho.
