draft-ietf-tls-applayerprotoneg-01 describes a registry for new
strings, but it does not describe what rules that registry operates
under, nor does it describe what information a registration is
expected to contain.

I'm going to suggest that "Expert Review" [RFC5226] is sufficient for
this registry.  Here's what I propose the document describe.

OLD:
   This document also requires the IANA to create a registry of
   Application Layer Protocol Negotiation protocol byte strings,
   initially containing the following entries:

   [... registrations ...]

   We propose that this new registry be created in a new page entitled:
   "Application Layer Protocol Negotiation (ALPN) Protocol IDs" beneath
   the existing heading of "Transport Layer Security (TLS)".

NEW:
  This document establishes a registry for protocol identifiers entitled
   "Application Layer Protocol Negotiation (ALPN) Protocol IDs" under the
   existing "Transport Layer Security (TLS)" heading.

   Entries in this registry require the following fields:

    Protocol: The name of the protocol.
    Identification Sequence: The precise set of octet values that identifies
       the protocol.  This could be the UTF-8 encoding [RFC3269] of the
       protocol name.
    Specification: A reference to a specification that defines the protocol.

   This registry operates under the "Expert Review" policy as defined
   in [RFC5226].  The designated expert is advised to encourage the
   inclusion of a reference to a permanent and readily available
   specification that enables the creation of interoperable
   implementations of the identified protocol.

   An initial set of registrations for this registry follow:

    Protocol: HTTP/1.1
    Identification Sequence:
       0x68 0x74 0x74 0x70 0x2f 0x31 0x2e 0x31 ("http/1.1")
    Specification: RFC 2616

    Protocol: SPDY/1
    Identification Sequence:
       0x68 0x74 0x74 0x70 0x2f 0x31 0x2e 0x31 ("http/1.1")
   Specification:
       http://dev.chromium.org/spdy/spdy-protocol/spdy-protocol-draft1

etc...
