A touch too strong for my liking. Perhaps "... and report for human
evaluation any subsequent checkgroups control message for the same
hierarchy or sub-hierarchy with a smaller &lt;chksernr> value or with no
&lt;chksernr> value.".

But even that seems to suggest that valid chechgroups should be accepted
on "auto-pilot", which is probably not a good idea.

But I am not pressing this too strongly if others are happy.
