functx:value-except
The values in one sequence that aren’t in another sequence
Description
The functx:value-except function returns the values in one sequence that do not appear in the second sequence, in an implementation-defined order. It removes duplicates, even among the values that appear only in the first sequence. This function is useful because the built-in except operator only works on nodes, not atomic values.
