Arghh... thats what an author like me deserves to get for not reading every bloody
formal language RFC line by line *sigh*.

Meaning i will remove the definition HEXLC and just use RFC5234 HEXDIG even though i
will keep lower case. Add a comment about preference to encode lower case but
need to absorb any case mix.

Thanks, Barry!
