We need to define the scope of what input strings will be accepted.  ISO-8601 defines a lot of stuff which we may not wish to accept.

Do we want to accept both basic format (YYYYMMDD) and extended format (YYYY-MM-DD)?

Do we want to accept things like "1985-W15-5", which is (if I understand this correctly(), the 5th day of the 15th week of 1985 [section 4.1.4.2].

Do we want to accept [section 4.2.2.4], "23:20,8", which is 23 hours, 20 minutes, 8 tenths of a minute.

I suspect most people who have been following the recent thread (https://groups.google.com/d/topic/comp.lang.python/Q2w4R89Nq1w/discussion) would say none of the above are needed.  All that's needed is if you have an existing datetime object, d1, you can do:

s = str(d1)
d2 = datetime.datetime(s)
assert d1 == d2

for all values of d1.

But, let's at least agree on that.  Or, in the alternative, agree on something else.  Then we know what we're shooting for.
