@darius I know you had a hobby of reading RFCs for fun, but sorry if this request is not welcome. :D
Would you mind to take a look at my extension to RFC3896 Section 3.4 (URL Query) syntax that I detail in this #FEP document[1]?
I have no previous experience with the way the RFC grammar syntax is defined and maybe you have more experience and can tell me if I made any mistakes in it. The rest of the document is far from done, so it can be ignored.

@mariusor oh sorry, I read RFCs from the very early days, decades before the grammar syntax was introduced. So I wouldn't be any help. (Cool proposal idea though!)
