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.
