Section 3.5 says:

x-sig-q-tag-args = qp-hdr-value

It should say:

x-sig-q-tag-args = dkim-quoted-printable  ; with ":" encoded

Notes:

sig-q-tag-methods are ":"-separated in sig-q-tag, so ":" shouldn't be permitted
within x-sig-q-tag-args. Note that qp-hdr-value (which I believe was originally
defined for sig-z-tag, which includes "|"-separated values) is defined as

qp-hdr-value = dkim-quoted-printable ; with "|" encoded
