     HEXLC = DIGIT / "a" / "b" / "c" / "d" / "e" / "f"

ABNF [RFC5234] is case-insensitive, so "f" in the grammar allows both
"f" and "F" in practice.  So the example does conform to the grammar.
That said, it's probably best to make the example internally
consistent and use all lower case letters, even though mixing them is
legit.
