The tags are indeed bad in the current state. But since there are 
applications already writing them, we can't change them anymore. So 
we'll have to deal with these bad news for the rest of our lives...

ProDoc has a good comparison of tag name "translations", and ARTIST 
commonly found is LEAD_PERFORMER in Matroska. An application should 
display "artist" in whatever language is used, not LEAD_PERFORMER...

We could consider the current tags as "beta" and clean them before 
"freezing" them. Before freezing we could ask for comments in various 
places (not very succesful in the past, but you never know). After all 
tags are only used in MKA (and one tag for video that won't change) 
which so far was experimental. Not much people could blame us (and they 
could still use foobar to change tag names)...

What do you (all) think ?

As was done with the format spec, we could introduce a "fix" HTML class 
for tags we know won't change, to show a difference when displaying them.
