I don't quite understand the discussion about ordering, but I can see the
importance of identifying individual tracks in a solid way.  Two notes:

1.  The random nature of serial numbers means that it is always possible
to edit a file, or add/remove tracks, without changing the serial number
of any track.  Current tools may or may not do this, but it is easy to do.

2.  It seems logical that one may want the ability to specify (in a
fisbone) human-readable unique identifiers for each track.  If a track has
such a name, that name can be used in lieu of its serial number.  (Files
with duplicate names would be ill-formed.)

Is there a list of standardized Skeleton fields?  I can't tell whether
there's a standard key for the name of a stream.
