we'll need relations of type=boundary to tag the borders properly.

there's always only ONE way to define a border. always use the highest 
appropriate admin_level, ie. if a district border is a state border as 
well, tag the way as a state border. no names or anything else here, 
just boundary=administratve and admin_level.

then intoduce several type=boundary relations, one for each 
administrative unit. for instance: if a district border is a state 
border as well but not a national border, then you'll need 4 relations: 
2 for the districts and another two for the states. the ONE border way 
is a member of all 4 relations.

hope i meda myself clear, if not see here:

or look a himachal, i corrected the borders there yesterday.

regards, micha
