what comes next? Have all the roads in a given administrative
area listed with an "administrates" role in the relation?
Cross-checking to me sounds like unhealthy redundancy here. It
means having to do the work twice and having the information
stored double.<br>

Redundancy??? Have you noticed that some borderlines are <b>hexaplicated</b>
(that they appear in 6 different relations) and that <b>that</b> is
unhealthy redundancy that is made unnecessary by subareas?<br>
<br>
And that, unlike wanting to destroy an enemy, the programs I spoke
of would be a great help building and checking the boundary ways
mess using the non duplicated, simple, clean
UK=England+Wales+Scotland subarea definitions?<br>

the various admin levels do not always form a strict

one of them, which might not be the next-highest level
(next-lower number).<br>

<div>in which way does a subarea role help here to solve real
problems? Which administrative
aspects/powers/relationships/fields are those that are
looked at? Do you have concrete examples?<br>

Read the messages and look at OSM.org.<br>
