Subject: [Bier] About the range of the SI value

Hi all,

It said in section 2 of the BEIR architecture draft (https://tools.ietf.org/html/draft-ietf-bier-architecture-04#page-6) that "A "BFR Identifier" (BFR-id) is a number in the range [1,65535]. "

It said in section 3 of the BEIR architecture draft that "SI is the integer part of the quotient (N-1)/BitStringLength"

It said in section 3 that "A BFR MUST support SI values in the range [0,15], and MAY support SI values in the range [0,255]." Assume the BitStringLength is allowed to be 64, the SI value should be in the range [0, 1023] instead of [0,255]. No?

Best regards,
Xiaohu
