Probably it is in the specification. The media people seem to have a
knack for coming up with idiotic stuff in their specifications...
I don't think the tag is required but probably not having it will break
some applications.
The names used are btw.:
Material file name: EXT:/PDR/default/b-lavf.gxf
Track file name: EXT:/PDR/default/ES.??
where the first ? depends on type (audio, video, timecode, and for video on the
codec) and the second ? increments with track number from 0..9 and then
there is a FIXME that 'A' should be next (but it's ':' that comes next).
I'd propose setting filename to e.g. "MUX.GXF" at least when bitexact is
set.
