Re: [xtm-wg] Q: F.6.4 Role player duplicate suppression

[Steve Pepper <pepper@ontopia.net>]

Graham, Kal,

I think Robert has a point that the wording in F.6.4 could
be clearer. It could be interpreted to refer only to members
that each have a single role-playing topic, leaving open the
question of what happens when one or more of the members
has *multiple* role-playing topics and the sets only overlap
but do not match.

One could argue that there can be no uncertainty if F.6.4 is
read in conjunction with F.3.3, but that is not immediately
obvious from F.6.4.

I give my interpretation below. Are we in agreement on this?
Do you think we need to improve the wording of F.6.4?

Yes.

No. But I agree that this could be clearer.
