+// 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:
+    cookie-av     = "Path"    "=" value
+                  | "Domain"  "=" value
