Section 4.4.1 says:
Length 4 Operator-Identifier The Operator-Identifier is a variable-length Private Enterprise Number (PEN) ...
It should say:
Length 4 Operator-Identifier The Operator-Identifier is a 32-bit Private Enterprise Number (PEN) ...
Either the length is 4, and the contents are 32-bits. Or the length is >1, and the length is variable.
My guess is that the intention is to have a fixed length. The variable-length encoding from RFC 6757 is likely not needed here.
