[M4IF Technotes] Short Headers and GOB

 From my interpretation of the MPEG-4 standard (document N4350) for what 
regards Short Header modality (section 6.2.5.2, "Video Plane with Short 
Header") it seems to me that putting GOB marker in the bitstream is 
compulsory and a stream without GOBs is not correct (however, this 
interpretation reduces the compatibility between MPEG-4 and H.263).
However, MoMuSys decoder decodes correctly both streams with GOBs and 
without GOBs.
Was my interpretation of the standard correct?
Best regards
