Hi Martin, I saw your previous message but was hoping someone have a definitive answer. Since nothing has surfaced, here is a fuzzy lead...
I have a (possibly unreliable) memory of this coming up during discussion of the unsupported vector grids module on the geotools-devel list last year or the year before. One use for that module was to cook up a display of areas of validity for projections in GeoServer. If you search through the geotools-dev list archives you might find the relevant thread: http://osgeo-org.1560.n6.nabble.com/geotools-devel-f4265016.html Alternatively, if Andrea or others read this they might be able to give you a more useful lead.
