Hi I am trying to use function op:divide-dayTimeDuration as declared at http://www.w3.org/TR/xquery-operators/#func-divide-dayTimeDuration http://www.w3.org/TR/xquery-operators/#func-divide-dayTimeDurationBaseX tells me either unknown namespace op, or unknown function.
Is this supported by BaseX, or I shall find my own implementation written in XQuery?
