Section B.1. says:

BIT            =  "0" / "1"

It should say:

BIT            =  %b0 / %b1

Notes:

The core rule BIT is written in the char-val rule syntax, which produces the ASCII chars %x30 ("0") and %x31 ("1"). For producing the 0 and 1 bit the bin-val rule should be used instead. Since the core rules use the hex-val rule extensively, using the bin-val rule shouldn't be a problem.
--VERIFIER NOTES--
No, the "BIT" construct is part of the "bin-val" construct, which gives "b0" or "b1", and "bin-val" is then part of "num-val", which is what produces "%b0" or "%b1". The ABNF is correct as written.
