Uhm, guys:
number = ["-"] 1*15 DIGIT
# XXX: Not sure how to do this in ABNF:
# XXX: A single "." allowed between any two digits
# The range is limited is to ensure it can be

Please notice:
1) If there is a period, it _has_ to be between to digits.
2) max 15 digits in total, so that people stuffing them in
ieee64bin aka double, don't get surprises.
