Relying on parameter entities substitutions for localization doesn't sounds a good idea to me, very fragile and relies on the most complex part of the XML-1.0 specification. For example a parser operating in non-validating mode of XML-1.0 is allowed to drop any declaration occuring in the internal subset after a parameter entity reference, and will do so without warning, fragile, very fragile ...
