+// clang-format off
+// The following comment block elucidates the function of ParseAttributes.
+/******************************************************************************
+ ** Augmented BNF, modified from RFC2109 Section 4.2.2 and RFC2616 Section 2.1
+ ** please note: this BNF deviates from both specifications, and reflects this
+ ** implementation. <bnf> indicates a reference to the defined grammar "bnf".
+
+ ** Differences from RFC2109/2616 and explanations:
+ 1. 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.
+ <LWS> according to spec is SP|HT|CR|LF, but here, we allow only SP | HT.
+
+ 2. We use CR | LF as cookie separators, not ',' per spec, since ',' is in
+ common use inside values.
+
+ 3. tokens and values have looser restrictions on allowed characters than
+ spec. This is also due to certain characters being in common use inside
+ values. We allow only '=' to separate token/value pairs, and ';' to
+ terminate tokens or values. <LWS> is allowed within tokens and values
+ (see bug 206022).
+
+ 4. where appropriate, full <OCTET>s are allowed, where the spec dictates to
+ reject control chars or non-ASCII chars. This is erring on the loose
+ side, since there's probably no good reason to enforce this strictness.
+
+ 5. Attribute "HttpOnly", not covered in the RFCs, is supported
+ (see bug 178993).
+
+ ** Begin BNF:
+ token = 1*<any allowed-chars except separators>
+ value = 1*<any allowed-chars except value-sep>
+ separators = ";" | "="
+ value-sep = ";"
+ cookie-sep = CR | LF
+ allowed-chars = <any OCTET except NUL or cookie-sep>
+ OCTET = <any 8-bit sequence of data>
+ LWS = SP | HT
+ NUL = <US-ASCII NUL, null control character (0)>
+ CR = <US-ASCII CR, carriage return (13)>
+ LF = <US-ASCII LF, linefeed (10)>
+ SP = <US-ASCII SP, space (32)>
+ HT = <US-ASCII HT, horizontal-tab (9)>
+
+ set-cookie = "Set-Cookie:" cookies
+ cookies = cookie *( cookie-sep cookie )
+ cookie = [NAME "="] VALUE *(";" cookie-av) ; cookie NAME/VALUE must come first
+ NAME = token ; cookie name
+ VALUE = value ; cookie value
+ cookie-av = token ["=" value]
+
+ valid values for cookie-av (checked post-parsing) are:
