Why should a boundary NOT have category too? How would you distinguish
two different types of boundary arround one area? Example on

http://les-ejk.cz/tmp/boundaries.gif

One country (Sachsen) has 2 different types of boundaries (country and
state).

I thing, it is usefull to have a possibility for adding category number
(and attributes) to boundary too.

Or do I understand it wrong?
