Dear Pancrazio, all,
please note that MPEG is currently in the process to ammend the MPEG-4 Audio 
standard as to specify the usage of mp3 content in an MPEG-4 compliant manner. 
There are actually two ways, one is already possible and is just denoted 
explicitly, while the other one is a real extension and will even allow for 
multichannel mp3 content.
Details can be found in the following output document (issued in Trondheim):
5717	Text of ISO/IEC 14496-3:2001/PDAM 3 (MP3onMP4)
This PDAM is currently under ballot (being the first of four ballots).
Best regards,
Ralph
