When I run that example with Saxon 8.7.3b I get the error:

 FORG0001: Invalid duration value 'P0Y3M3DT12H' (non-numeric or
out-of-range component)

..so your duration value isn't valid.  You appear to have included
years and months, whereas it only allows days and a time (the allowed
format is "PnDTnHnMnS") see:

http://www.w3.org/TR/xpath-functions/#dt-dayTimeDuration

Also, I believe the only prefix to use these days is xs:* (although
Saxon seems to work with both).
