My understanding is that since auth-scheme ends with a token and
auth-param starts with a token, LWS is implied by the BNF:
implied *LWS
The grammar described by this specification is word-based. Except
where noted otherwise, linear white space (LWS) can be included
between any two adjacent words (token or quoted-string), and
between adjacent words and separators, without changing the
interpretation of a field. At least one delimiter (LWS and/or
separators) MUST exist between any two tokens (for the definition
of "token" below), since they would otherwise be interpreted as a
single token.
However, for consistency and readability reasons, it should probably
be made explicit, like in the challenge case:
challenge = auth-scheme 1*SP 1#auth-param
Alex.
