Also:

-----------------------------------
 This is determined by the following from the definition of ABNF in RFC
 2234 (now superseded by 4234):
 
 ABNF permits specifying literal text string directly, enclosed in
 quotation-marks. Hence:
 
 command = "command string"
 
 Literal text strings are interpreted as a concatenated set of
 printable characters.
 
 NOTE: ABNF strings are case-insensitive and
 the character set for these strings is us-ascii.
 
 Hence:
 
 rulename = "abc"
 
 and:
 
 rulename = "aBc"
 
 will match "abc", "Abc", "aBc", "abC", "ABc", "aBC", "AbC" and "ABC".
