With XQuery 3.0 enabled, a FLWOR expression may contain multiple where clauses. For example for $c in customer where $c/credit > 0 where $c/region = 'EMEA' The effect is exactly as if the clauses had been separated with the "and" operator.
for $c in customer where $c/credit > 0 where $c/region = 'EMEA'
