Terry, I liked these ideas so much I removed both "integer" and "float" from the HTTP-NG type system. See http://www.parc.com/janssen/pubs/http-next-generation-architecture.html, section 4.5.1. Though if I was doing it again, I'd go further, and make all fixed-point, floating-point, and string types abstract, so that only application-defined concrete subtypes could be instantiated. Bill
