I am trying to add dates and duration through BaseX, in conformance with http://www.w3.org/TR/xpath-functions-30/#func-add-dayTimeDuration-to-date.

However, BaseX interpreter does not recognize the function add-dayTimeDuration-to-date, nor op:add-dayTimeDuration-to-date.

Did I misunderstood something ?

Thanx for your answer,

Cheers,

Jean-Marc
