This is a follow-up to today's decision on casting xs:duration to string (bug
1292) in which we decided that an xs:duration of P24M should convert to the
string P2Y.

This raises the question, what is the value of
years-from-duration(xs:duration('P24M')). Is it 0 or 2?

We don't seem to have any text or examples to tell us the answer. Extrapolating
from the behavior of xdt:yearMonthDuration suggests the answer is 2, but we
should say so explicitly.
