Description

The functx:total-years-from-duration function returns the total number of years in $duration. If it is an uneven number of years, it will return a fractional part. This function is different from the built-in fn:years-from-duration function because the latter will not return a fractional part. If $duration is the empty sequence, the empty sequence is returned.
