To a certain extent, yes. The idea is, as always, to reduce confusion=

I was thinking of such examples, and this is why I added "if both are=
 to be=20
defined". Most probably Lipotyphla and Archonta will simply not be de=
simply because their contents are no longer thought to form one clade=

(Wasn't Euornithopoda once such a case? Or was this a misinterpretati=
on by=20
the secondary literature?)

This is a case like *Euparkeria*. As I mentioned, cases like these sh=
(most probably) be explicitely allowed to stay, consistency with the=
literature outweighing the small possible confusion.
