SIP protocol - Independent of transport layer

Hi, I find that,SIP is designed to be independent of the underlying transport layer; it can run on Transmission Control Protocol (TCP), User Datagram Protocol (UDP), or Stream Control Transmission Protocol (SCTP). Then, why is the SIP protocol referred as a " TCP/IP-based Application Layer protocol " ? Any ideas ?
