On December 1st, revision 10 of the XES Standards Proposal was approved by the IEEE XES WG. This revison was updated into revision 11 (the month in the header was updated), which has been submitted on December 2nd for Mandatory Editorial Coordination (MEC).

MEC is required prior to start of a ballot. Its goal is to ensure conformance with IEEE requirements, which may reduce the number of recirculations and helps to avoid delays in approval (or possible rejection) by the IEEE new standards revision committee (RevCom).
