(1) The most important item which might be missing for anime is Seiyu 
(Voice Actor, Voice Actoress), but one can use the ACTOR tag for Seiyu 
too. It might be a good idea to explicitly add about that to the ACTOR's 
definition. like "...including a voice actor/actress (Seiyu) for anime"

Another thing related to anime that is less important but might be 
welcome would be :

(2) I'm not insisting this, but hypothetically speaking, there could be 
some tags for a subtitle track--not only for video and audio--, and if 
they were, they would be:

(3) As for 'Technical Information' it might be a good idea to add one 
about the color space, especially RGB_RANGE to distinguish PC Scale and 
TV Scale.
In the future, there might be a smart video renderer for PC that 
converts 16-235 to 0-255 only when the input RGB range is 16-235, and 
does not convert that if the input is 0-255 (already optimized for PC); 
so, it might be a good idea that MKV can tell the renderer about the 
RGB_RANGE used in video encoding.
Today, ppl are often annoyed to see video rendering systems perform 
16-235 to 0-255 conversion even tho the input is already 0-255 (PC 
Scale), i.e. needlessly converting doubly, resuting that bright colors 
will white out and dark colors will black out.

That's it. Just some random thoughts
