Yes, that is according to the spec (=expected).

Well, apart from the fact that it is documented (see above), the ISO date
format and general usage has year/month/day. So week would be another animal.
I know in Germany we have these "KW" (calendar week) numbers, but I'm not
sure if something like this is usual internationally.
See https://en.wikipedia.org/wiki/ISO_week_date
It's not trivial to come up with a coherent week numbering system but
I guess we could implement ISO 8601 week numbers (in some form) if
there's a real use case for them.
