The NETCONF messages exchanged between the server and client are
serialised XML and validation means that the other side is able to tell
whether the received data are legal. It's not so important whether you
perform this check on the serialised XML, DOM tree or otherwise. YANG
draft always speaks about XML representations and nothing else.

I agree, yet even in this case the distinction between (i) and (ii)
holds, after changing "XML documents" to "configuration data".
