> If we map any ObjAttributes of an entity to custom value types that do not have a repeatable toString, our cache keys will stop working if these types are used as qualifier parameters. 
> Per CAY-2050 ExtendedTypes now support unique toString. Perhaps we use this or a similar method for cache key generation (actually can't use ExtendedType.toString directly for the types that are trimming their display values, like arrays and Strings, so we'll need to amend that API to use for cache keys).
