Note
The value of the when attribute should be the normalized representation of the date, time, or combined date & time intended, in any of the standard formats specified by XML Schema Part 2: Datatypes Second Edition, using the Gregorian calendar.
The most commonly-encountered format for the date part of the when attribute is yyyy-mm-dd, but yyyy, --mm, ---dd, yyyy-mm, or --mm-dd may also be used. For the time part, the form hh:mm:ss is used.
Note that this format does not currently permit use of the value 0000 to represent the year 1 BCE; instead the value -0001 should be used.
notBefore specifies the earliest possible date for the event in standard form, e.g. yyyy-mm-dd.
