This is not the topic of this thread, but since you brought it:
If you take a look at the description patch in the patch I sent, the
problem I outlined is that at create time, we don't know anything about
which will the css_id be - and I would like to avoid creating yet
another index.

Is there any way you would suggest of handling this ? Any chance of us
allocating the css_id earlier then?
