xdt:yearMonthDuration that corresponds to the difference between
the normalized value of $srcval1 and the normalized value of $srcval2. If
either argument is the empty sequence, returns the empty sequence. If the
normalized value of $srcval1 precedes in time the normalized value of
$srcval2, the returned value is a negative duration.
