This is true for every extension of the standard with a new object type,
right ? 
Yes. And it also indicates that MPEG is *very* careful adding new stuff. New
things have
to bring *major* improvements. At this point, when we are talking about MPEG
Video
coding, new proposals are entertained in the context of the Joint Video
Team, the 
cooperation of ITU-T and MPEG for the next-generation Video Coding Standard.

With this mail, I want to close this discussion. If there are further
questions on the issue, 
please send them to me exclusively.
