Section 5.3.2 says:

<number> ::= any decimal integer 1 through 255

It should say:

<number> ::= any decimal integer 0 through 255


if 0 is not allowed, one cannot even represent with
<host-number> ::= <number>,<number>,<number>,<number>

[Verifier Note: This does allow syntactically for nonsense values for <byte-size>, <port-number>, and <host-number>, but this was also true in the current syntax.]
