Have you consider having the first line just say that it returns true if an identifier is a simple identifier? I'm asking because "Retrieves" is confusing here. There is no leeway in the specification to allow for different implementations to have a different outcome. No issue with driver implementations that consult with the database to get a result but it doesn't change the outcome.
