    A NamedList is a proper "heatmap" response if it contains all expected properties We try to be rather strict in determining whether potentialHeatmapValues is a "heatmap". Users can name subfacets arbitrarily, so having some names match those expected in a "heatmap" response could just be coincidence.
    Heatmap facets do not support subfacets.
