For me it seems bad to design some systems in English like public administrations software or following a law very closely (there are even no translated concepts in things like taxation and legal system) and data exchange formats should be in the language it matters (for example, all electronic bills in Spain are XML with entities in Spanish), so if you want a 1:1 mapping you need to use native language.
