Yep I know this is "one of these cases" - this is partly why I am so
enthusiastic to see it being addressed :-)
The nature of this change (effecting other modules) does put it in proposal
territory; and we really need to get feedback from effected modules
(specifically gt-render). I am available on IRC if you want to chat through
these issues.
As indicated I am enthusiastic for this change and think it is a good idea; we
just need to sort out the consequences.
If you read aaime's email he was going through some of the expectations for
xpath evaulation. I don't have a sample xml file and xpath tool to answer those
questions - but tin my very first email response to this subject I indicated
that I would like to see us match the xpath experience (so that the Filter and
SLD data structures we produce are indeed handled correctly).
