I fully agree.

Note that we already have element awareness for RDFa in (X)HTML: the
base element is treated (very) specially, as is head and body
(implying @about). Thus special processing of the content of <time> in
HTML should be quite ok.

I also think we should consider whether xsd:gYear, xsd:gYearMonth and
xsd:gMonthDay can be captured as well (since years less than 1000 must
be padded with leading zeros [1]). Of course, xsd:gMonth and xsd:gDay
are too ambiguous, as today's date so amply indicates. ;)

Best regards,
