And I would agree.  "Is manifest in" ranges over something that looks like a
context or a manifested document.  So I think that we will need both
relations "is instance of"  and "is manifested in" to model our situation.
Please see the mentograph:

Note the difference between this and the last one:
where I tried to make statings a class.   I like your way better, but now we
need to agree on a good name for the relation that I put in red.

I would also like to note that now that the WG has all but decided on
statings rather than statements, that the 'C' word (Context) which you have
introduced here lurks naturally around the corner :)
