Maybe this is a very stupid question: Doesn't support GeoTools the use of the
EPSG database for getting the transformation parameters? AFAIK most CRS are
exactly defined in the EPSG database (including Bursa wolf parameters and other
means of reprojection), so all missing information can be retrieved from it,
cannot it?
Since I'm interested in the reprojection functionality myself, maybe someone can
shortly outline to me how this currently handled in uDig/GeoTools2.1.
