I'm giving this a size of 10 to investigate but it might take more effort to actually fix it. Generally, our facets operate in a single language but the datasetType facet was designed to be internationalized. Like @qqmyers says, we may need to have the facet operate on an underlying constant number or string rather than any particular language.
