functx:total-days-from-duration
=============================== 

The total number of days in a dayTimeDuration

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