const AUTHORIZATION_TOKEN: u64 = 0x01;Expand description
AUTHORIZATION TOKEN, the Version Specific Parameter of Section 8.2.1.1.
The number is this draft’s own. Draft-11 assigns AUTHORIZATION TOKEN “Parameter Type 0x01”; drafts 12 and 13 move it to 0x03 and leave 0x01 to the setup-side PATH parameter. Reading either draft’s number into the other would exempt the wrong type from the repeat rule below.
