1048 /* TODO:
1049 We are currently not able to fully support a switch to another calendar during
1050 input for the following reasons:
1051 1. We do have a problem if both (locale's default and format's) calendars
1052    define the same YMD order and use the same date separator, there is no way
1053    to distinguish between them if the input results in valid calendar input for
1054    both calendars. How to solve? Would NfEvalDateFormat be sufficient? Should
1055    it always be set to NF_EVALDATEFORMAT_FORMAT_INTL and thus the format's
1056    calendar be preferred? This could be confusing if a Calc cell was formatted
1057    different to the locale's default and has no content yet, then the user has
1058    no clue about the format or calendar being set.
1059 2. In Calc cell edit mode a date is always displayed and edited using the
1060    default edit format of the default calendar (normally being Gregorian). If
1061    input was ambiguous due to issue #1 we'd need a mechanism to tell that a
1062    date was edited and not newly entered. Not feasible. Otherwise we'd need a
1063    mechanism to use a specific edit format with a specific calendar according
1064    to the format set.
1065 3. For some calendars like Japanese Gengou we'd need era input, which isn't
1066    implemented at all. Though this is a rare and special case, forcing a
1067    calendar dependent edit format as suggested in item #2 might require era
1068    input, if it shouldn't result in a fallback to Gregorian calendar.
1069 4. Last and least: the GetMonth() method currently only matches month names of
1070    the default calendar. Alternating month names of the actual format's
1071    calendar would have to be implemented. No problem.
