Surely that's precisely what @datingMethod is for? <date
when-custom="3050" datingMethod="#anno_mundi"/> means I'm normalizing a
date to the AM calendar (which is defined in a <calendar> element with
The distinction between @calendar and @datingMethod is very clear (the
former defines the content of the element, the latter the @*-custom
attributes). Martin's suggestion is premised on the fact that in all of
the examples we are imagining the two are the same, so it seems an odd
redundancy to say:
<date from-custom="1547" to-custom="1633" calendar="#julian"
Which is indeed a pain (I might be inclined to say that when
@datingMethod is absent, we assume the *-custom attributes follow the
same calendar as defined in @calendar, but that makes me slightly nervous).
But consider the following cases where the transcribed date and the
non-Gregorian normalization are different calendars. It is the norm in
classical studies to normalize all dates to the proleptic Julian
calendar, to avoid saying something like: <date when="-0044-03-13">the
Ides of March</date> (which should be March 15th). This is true even if
the date we're encoding is not Julian, but in some other form: "Pachon
19, 12th year of the reign of Tiberius" or "11 October, 4th Indiction"
For these we'd use something like @calendar="#romano-egyptian"
I'm not sure it's a very good idea to expect @calendar to serve double
service as Martin suggests...
