IETF SHALL keep JTC1/SC6 informed of TLV codepoint values allocated, and JTC1/SC6 SHALL refer allocation requests arising within JTC1 constituencies to the IANA registry process.
Codepoints greater than 255 can only be used in PDUs designated to support extended TLVs.

For future codepoints, in cases where the document that defines the encoding is different from the document that assigns the codepoint, the encoding reference MUST be to the document that defines the encoding.
If a link attribute can be advertised both as a sub-TLV of TLVs 22, 23, 25, 141, 222, and 223 and as a sub-sub-TLV of the Application-Specific Link Attributes sub-TLV defined in [RFC8919], then the same numerical code should be assigned to the link attribute whenever possible.
