Saxon

Scenario:

$key is a key enabled with saxon:range-key="true", and $key has no entries in the range $min to $max for document $doc

Expected behavior: saxon:key-map($key, $doc, $min, $max) returns an empty map.

Actual behavior: saxon:key-map($key, $doc, $min, $max) returns all entries whose key values are above $min.

Reproducible: The following script, when processed by Saxon 9.5.0.2 returns the output

1 2

9

The "9" is unexpected. I searched saxonica.plan.io for tickets associated to saxon:key-map() and did not find any, so I assumed this has not been resolved.
