apparently not:-)
So here is a fix (just a change to the light red clause)

<root>
  <arbitrary/>
  <red>
     <elem color="dark-red"/>
     <elem color="red"/>
     <arbitrary color="none"/>
     <elem color="red"/>
     <elem color="light-red"/>
     <arbitrary/>
  </red>
  <arbitrary/>
</root>

<root>
  <arbitrary />
  <elem       color="dark-red" />
  <elem       color="red" />
  <arbitrary  color="none" />
  <elem       color="red" />
  <elem       color="light-red" />
  <arbitrary />
  <elem       color="dark-red" />
  <elem       color="red" />
  <arbitrary  color="none" />
  <elem       color="red" />
  <elem       color="light-red" />
  <arbitrary />
</root>

<root>
  <arbitrary/>
  <red>
     <elem color="dark-red"/>
     <elem color="red"/>
     <arbitrary color="none"/>
     <elem color="red"/>
     <elem color="light-red"/>
     <arbitrary/>
     <elem color="dark-red"/>
     <elem color="red"/>
     <arbitrary color="none"/>
     <elem color="red"/>
     <elem color="light-red"/>
     <arbitrary/>
  </red>
  <arbitrary/>
  <red>
     <elem color="dark-red"/>
     <elem color="red"/>
     <arbitrary color="none"/>
     <elem color="red"/>
     <elem color="light-red"/>
     <arbitrary/>
  </red>
  <arbitrary/>
</root>

That is of course if I've scaled up the input correctly, no comment
from the OP so far.

cheers
