Good question! We agreed that timeformat is optional but we have said nothing about timeunit. - Case 1: timeunit is optional, default is 'second' ? - Case 2: timeunit is mandatory I observe that xywhunit is optional!

Do someone remember? I remember we agreed to not predefine any track name, since we couldn't find in the existing container format a coherent naming scheme for the audio, video, etc. Davy, can you confirm? Cheers!
