Hello! Here, I am suggeting a small (but probably useful) improvement to the EDTF specification. What do you think about adding the following new feature at #103 (or maybe #205) 2008-21/open which could for example be really useful to store the publication date for a journal first issued in "spring 2008" and still publish four times a year (spring, summer, fall and winter - in any order)? The BNF could be really easily modified for that, just replacing > L1Start = (date UASymbol?) | "unknown" with L1Start = ( ( date | season ) UASymbol?) | "unknown" Regards! SaaĊĦha,
