months and years durations were deliberately excluded due to 1. Lack of documented use-cases/publishing examples for them. 2. Precedent. Explicit exclusion of month and year durations from iCalendar (which was the basis for hCalendar, which was a key design driver for the time element).

What is more, it pukes on durations that include months, apparently because someone thought that M is ambiguous as between months and minutes. This is not the case, because M means minutes only after a T has been seen in 8601, whereas HTML5 is apparently permissive about T. I do wish the spec would provide either prose or code, rather than code masquerading as prose. So this is a case of failing to accept a syntax that is in the lexical and the value space of XML Schema. -- John Cowan cowan@ccil.org "Mr. Lane, if you ever wish anything that I can do, all you will have to do will be to send me a telegram asking and it will be done."
