cast the dutchie on the right hand side

[Ihe Onwuka]

So I naively thought I'd try

xquery version "3.0";

('1999-12-31','2003-11-04') / castable as xs:date

because I am dealing with dirty data that shouldn't but sometimes contains
more than one date field.

Am wondering what is so objectionable about mapping a Boolean operator over
a sequence?

This should help you:

('1999-12-31','2003-11-04') ! (. castable as xs:date)
