Currently, EntityIdValues are represented in JSON as pairs of entitiy types and numeric ids. There is no eay for a client to mak this to a prefixed id or URL. Instead, we should always use the prefixed ID form (e.g. "Q1234") to represent an entity ID externally (and probably also in the internal serialization). Of course, we must keep accepting the old form as input. Otherwise, we would be unable to process serializations from existing revisions.
