I try to be a bit more expressive in the aut-num of ASN199284, but
fail to get accepted at least the valid parts by the RPSL parser.
rpsl(ng) hasn't seen any significant development work since the 1990s,
and the only real update since then was to support ipv6 (rfc4012 in
2005). The only functional parser out there, irrtoolset, is crippled
with functional shortcomings and is basically abandonware.
You may want to think twice about whether it's worth investing time and
effort in rpsl in 2020.
