On LC’s EDTF page ( I just noticed: “The draft specification is to be superceded; EDTF functionality has been integrated into a draft revision of ISO 8601 to be published in 2017 or 2018.”


This is the first I have heard of this, and am afraid I have missed conversations elsewhere on the topic. Are others following the new ISO 8601 draft (and omitting |2 coding in 046)?
