Right, Explanations can be of different dif. level within a topic and
this can be changed by the author. I don't remember what we stopped at
in this discussion, meaning that there can be yet another dif. level,
which is voted. These two dif. levels must not be tied. Actually, I
wrote few times about the issue and want it be taken into consideration.

Also, the same explanation cannot be used in another topic of the same
course, this wouldn't make any sense.

I thought - we replaced the course idea with user group. At the very least, I can make a unique index for the TLT and explanation id to enforce your latest requirement.
