Thanks for the links but they do not completely answer my question. Let 
me rephrase. In some cases the MSE spec says:
"Queue a task to fire a simple event named change at the 
HTMLMediaElement track lists that were modified."
for instance when changing the kind, language of a track or when 
removing a source buffer. But when processing an initialization segment 
such sentence is not used, for instance, it only says:
"Add new audio track to the audioTracks attribute on the HTMLMediaElement."
I think it could be clearer.
