Our conversion from CLDR's format to our own was missing some things it could support sensibly, and some it could do better than ignore or treat as literal, while mis-handling the 'E'-based formats for day names. At least in CLDR v34 this doesn't actually make any difference (on regenerating our locale data, the only change is the date of generation).
