* CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)>

* SEP = one of the 17 defined separators or SP or HT
|
|
* LWS = CR, LF, SP or HT
|

* SPHT = SP or HT. Use this macro and not a boolean expression for best speed.

* token = any CHAR except CTL or SEP. Use this macro and not a boolean expression for best speed.

|
|
* added for ease of use:
|
|
* ver_token = 'H', 'P', 'T', '/', '.', and digits.
