This is not entirely true. Only the first id mapping must refer to root. 
And by first I mean in a sorted array of mappings. For instance:

<idmap>
   <uid start='1' target='1001' count='1'/>
   <gid start='1' target='1001' count='1'/>
   <uid start='0' target='1000' count='1'/>
   <gid start='0' target='1000' count='1'/>
</idmap>

is okay.
