Thanks. If I understand, you mean it might be worth a try to implement 
this. For us it would certainly simplify, and reduce mistakes/confusion.

I've yet to look into the code, but I will try and do this. If you have 
any hints or recommendations where to begin then that'd be good.

I think I did peek some years ago to find out that it was non-trivial, and 
then came up with the script!

I wonder if there are any users who are granting permission to specific 
branchs or tags or tag directories. I'm not sure if this is really a valid 
use case, but there might need to be a way to ignore the top-level 
attributes too for some special cases?

Thanks
