Okay, that helps me to grasp this. And yes, I can see that approach: Any
number of "participants", with the possibility of marking any number of
them as principal.

And I can see also the approach of showing or hiding that functionality
for different "tag types" (or whatever discriminatory basis). For
example, typically, it would be appropriate only to have one principal
in a death, and the program user might well be prevented from entering
the deceased, the doctor, the paramedics, the spouse, etc., as principals.

Side comment on this issue: I have no problem conceptually with making
only the HOH or the HOH and spouse the only principals for a Census
entry. In fact, were it possible to know, I'd prefer to put only the
interviewee as the principal.

No matter how we use witnesses in our Census entries, IMO it's a whole
lot better than what I did in FTM, a separate "tag" for each person for
each Census.
