HTTP Alternative Services (Alt-Svc) are identified by a tuple of Application-Protocol Layer Negotiation (ALPN) protocol identifier, a host and a port. The wire format for Alt-Svc is defined in ABNF and encodes this tuple or the keyword "clear", which has a special meaning. This memo reserves the ALPN protocol identifier "clear" to reduce the chances of accidental aliasing with the "clear" keyword.
