Hello,
We, at Greenpeace, would like to add the "localization data" into the message catalog but since we are not using the latest version from acs-lang (instead our own gp-lang) I don't know how usefull it will be...
I will try to keep Lars and Peter informed about the development here so that they can re-use the work done here...
Hope this is at least something that you will find useful.
