[Bug 21370] [w] component specifier in date/time formatting is ill-specified

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21370

--- Comment #1 from Michael Kay <mike@saxonica.com> ---
Yes, I agree it's problematic. In my XSLT 2.0 book I say "ISO 8601 does not
define a numbering for weeks within a month. You will have to see what your
implementation returns".

The difficulty is that [w] is available in XSLT 2.0, even though
underspecified, so removing it has its own problems. We could

(a) attempt a specification of what it means

(b) say that the result is implementation-defined

(c) say that it's implementation-defined whether [w] is supported

(d) withdraw or deprecate it

I'm going to specifically ask for XSL WG discussion of this.
