    Using OBJECT elements for dates would be plainly insane. An OBJECT is a heavyweight intruder with incompatible content, whereas a date is a perfectly short plain text. Moreover, the data attribute contains an URL, so data=”mmddyyyy” would result in requesting , which would be a rather undesireable artefact.
    The problems with Safari are very small compared to these objections.

    Hi Andy,

    +1 from us on all of that, esp. the use of “schema” for non-ISO8601 dates coupled with defaulting to ISO8601 if not specified. That’s exactly what standards like ISO8601 are there for!

    For right now in the pre-HTML5 WWW, to bring up your idea of adding “data:” on the front of the title in the span for dates in microformats, do you have any examples “in the wild”? Any idea how YQL etc. react to the addition of the word “data:” on the front of the date? Borking out?

    We want to use microformats along with all the exciting things that they open up – most yet to come – but not if it’s a major detriment to Accessibility.

    Keep fighting the good fight!

    See also Extended Date Time Format efforts based at the USA’s Library of Congress.

    The latest vCard draft includes a CALSCALE (calendar scale) property, which is equal to the “schema ” property I proposed above.

    There is now a WHATWG wiki page gathering evidence and use cases for the TIME element in HTML5.
