[zeromq-dev] RFC citation format

[Justus Ranvier]

The specifications on https://rfc.zeromq.org/ internally refer to 
themselves using only the domain-specific index number (e.g. 27/ZAP)


Is there a canonical citation format defined which a document in a 
different project with its own identification scheme could use to refer 
to ZeroMQ specifications?


As an alternate question, I noticed that the description on the site 
itself is pretty open ended stating, "We collect specifications for 
APIs, file formats, wire protocols, and processes" even though unless I 
missed something the only specifications present are the ones 
implemented by libzmq.


Was that site intended to be a general collection point for 
ZeroMQ-related specifications? Is that the best place to publish the 
specification for a ZeroMQ-based wire protocols that won't be 
implemented by libzmq itself?
