Re: [xml-dev] Incompleteness of Duration

To the extent that ISO is a culture all to itself (the ISO definition of a week does not align with traditional Christian, Islamic or Jewish calendars but does seem to be well suited for the Western working week), Mike's point about the start, definition and numbering of weeks seems to be reinforced by your comment.

There is, however, an ISO standard: weeks begin on Monday, and the first
week of the year is the week containing the first Thursday in January.
Thus 2005-01-01, a Saturday, is synonymous with 2005-W53-6, the sixth
day of the 53rd and last week of 2004.

Note that XSD time does not include leap seconds, which means that the
XSD 1.1 value space for durations contains <second, month> pairs.
There are a fixed number of seconds in a minute, hour, and day, and a
fixed number of months in a year.
