Nothing new here, except for an additional optional 'Language' tag...

The latter will be use for the tag MainSound.

Contrary to what one might think, Dolby & DTS sound tracks do not use MainSound at all but instead use AuxData...

Conclusion

SoundTrack - used by MainSound - is the second main element in a DCP.

The main asset MXF audio - depending on the audio configuration - may include additional elements such as synchronization data (used by Immersive Audio Bitstream / Atmos), MotionData (used by DBOX), and tracks tracks for the deaf and hard of hearing, amonth others..
