Resolve the descriptor label for an attribute score against its
value-description bands. Bands are considered in ascending maxValue order;
the descriptor is the label of the first band whose maxValue is at least
the score. When the score exceeds every band, the highest band's label is
used; when there are no bands, the descriptor is the empty string.
