It does not matter since the hex digit is case-insensitive.
RFC 4646 says:
UNICHAR = "&#x" 2*6HEXDIG ";"
and refers to RFC 4234 which says:
HEXDIG = DIGIT / "A" / "B" / "C" / "D" / "E" / "F"
(And strings in ABNF are case-insensitive)
As Frank Ellermann reported, the currently-discussed Internet-Draft
draft-klensin-unicode-escapes-01 may be relevant here. See
for instance (and https://www1.ietf.org/mailman/listinfo/discuss if you
want to participate).
