The spec only allows/validates US/English style numbers as the field
*value*, but the UI (and hence display) of the number should respect
the locale.

Similarly, for dates, the value is always given in ISO format. The
*display* can be anything, but the script and the server won't know
and won't care.

(Ian, I think you need to clarify this in the spec. It talks about
  "submission" formats, but not about the format in which the value
  must be stored in the DOM.)

I'd say that for dates, you need a few keyword values.
For numbers, you need to be able to say "append/prepend this unit".
(Currencies are covered under the "number" input type.)

In neither case is a full-fledged format string necessary.
