    RFC2622 uses the following Flex macro for AS numbers --

INT            [[:digit:]]+
ASNO        AS{INT}

   Note that this does not limit the length of the AS number.   While
it's no guarantee that an RPSL tool wouldn't break with longer AS
numbers, it would seem less likely than with the "." notation.
