OK > if you find this unclear, feel free to contribute better text. I have to agree that the spec is already clear enough. Sorry for how I asked the question. Maybe you could improve the first sentence of sec. 6 to say:: "The Interface identifier format is based on the format specified in section 2.2 of [RFC6052], with the added PSID format field, or with an IPv4 prefix instead of an IPv4 address."
