   Just wondering...
   If the translations I am getting (XtGetValue) went through the
   resource conversion mechanism, the parsed translations are cached,
   so the (opaque) handle I get remains valid forever.

   However, if the translations I am getting is something set by
   the application or some other widget, I am not quite so sure.

   On the other hand, all the (opaque) translation handles are
   "created" by XtParseTranslations (XtOverrideTranslations....).
   Do those call "cache" the translation structure(s) so that
   the (opaque) translations handle is always VALID ?
   (I don't see any XtFreeTranslations call -).
