Claus,

Comments below, as usual.  (I must figure out how to define a macro.)

<JC>
I guess then we will have to leave this until issue 1 is resolved.

<JC>
And in V2?

As you point out yourself, this could end up as a very complex query.

The TN approach supports both V2 and V3 with relatively efficient queries.

You can, of course, also do the more precise queries you want to do with the
TN approach.
