I think so. That should be true, shouldn't it?

I had thought so, but then I realized I wouldn't want to enforce either 
of those things. If @calendar points to a <calendar> with a detailed 
description of the dating system, then there's no point in @datingMethod 
(which also "supplies a pointer to a <calendarDesc> element or other 
means of interpreting the values of the custom dating attributes". 
(Incidentally, should that be <calendarDesc> or just <calendar>?) 
Similarly, @datingPoint is obviously optional.

However, I think it's true to say, isn't it, that if you have any of 
@*-custom, you should have one of @calendar, @datingMethod or @datingPoint?

Cheers,
Martin
