    public static final class CatalogAttribute.FacetConfig.MergedFacet.Builder extends GeneratedMessage.Builder<CatalogAttribute.FacetConfig.MergedFacet.Builder> implements CatalogAttribute.FacetConfig.MergedFacetOrBuilder

The current facet key (i.e. attribute config) maps into the
merged_facet_key.
A facet key can have at most one child. The current facet key and the
merged facet key need both to be textual custom attributes or both
numerical custom attributes (same type).
