functx:value-intersect
The intersection of two sequences of values
Description
The functx:value-intersect function returns the intersection of the values in two sequences (values that appear in both sequences) in an implementation-defined order. It removes duplicates. This function is useful because the built-in intersect operator only works on nodes, not atomic values.
