13// XXX Bugs to file:
14// XXX any trailing spaces: -> exception for +[NSCalendarDate dateWithNaturalLanguageString]:
15// > NSCalendarDate dateWithNaturalLanguageString: '12 '
16// format error: internal error
17
18// XXX NSDate natural language stuff in NSCalendarDate (why?), misspelled category name
19// XXX NSCalendarDate natural language stuff behaves differently from NSDateFormatter (AM/PM has no effect, shouldn't they share code?)
20// XXX NSDateFormatter doc class description gives two examples for natural language that are incorrect, no link to NSDate doc that describes exactly how natural language dates are parsed
21// XXX NSTimeFormatString does not include %p when it should, meaning that AM/PM is stripped yet 12-hour time is still used
22// XXX NSNextDayDesignations, NSNextNextDayDesignations are noted as 'a string' in NSUserDefaults docs, but maybe they are actually an array, or either an array or a string, given their names?
23// XXX "Setting the Format for Dates" does not document how to get 1:15 AM, the answer is %1I - strftime has no exact equivalent; the closest is %l. strftime does not permit numeric prefixes. It also refers to "NSCalendar" when no such class exists.
24// XXX none of many mentions of NSAMPMDesignation indicates that they include the leading spaces (" AM", " PM"). In "Setting the Format for Dates", needs to mention that the leading spaces are not included in %p with strftime.
25// XXX descriptions for %X and %x are reversed (time zone is in %X, not %x)
26// XXX too hard to implement date-only or time-only formatters
27// XXX should be able to specify that natural language favors date or time (10 = 10th of month, not 10am)
28// XXX please expose the iCal controls!

If we could get the active text field somehow via public API (guess we could use controlTextDidBegin/controlTextDidEndEditing) then we'd not need to overload the update sender for this purpose. Or, I guess, we could use another method other than update. It should not be this hard to implement what is essentially standard behavior. Sigh.
