The rumor started off-list, as a heads-up about a change to both the
attribute and IDL name. It was then discussed during our last telecon,
but we could not find anything regarding the attribute name, other
than that it has always been called @datetime (for 14+ years).
Thankfully, it is now clear that only the IDL changed, which as said
does not affect RDFa at all.

Thanks for your investigation and clearing up of this! Everything is
thus fine regarding the @datetime attribute name.
