bool elem->on_subdomain(S) const
{ return (_sid & S); }
Or something like that? Of course care must be taken to set _sid originally??
Some kind of
void elem->add_to_subdomain(S)
...
??

Elaborate?
My brightest idea:
We have a potentially-hybrid subdomain of subdomain_id N, we start
writing it out with Exodus_id N. each time we see a new element type
we assign Exodus_id N+magic_max_id_number to it.
We start reading in elements; if any of them have a larger Exodus_id
than magic_max_id_number then we give them a subdomain_id of
Exodus_id%magic_max_id_number.
As long as magic_max_id_number is less than max_Exodus_id /
max_number_of_element_types then we're fine.
I think Jed recently mentioned inventing his own file format in a very
apologetic tone; at the time I was thinking that although reinventing
the wheel is a bad idea in general, it might be justified when your
selection of existing wheels is limited to a hexagonal design, an oval
design, a design made from concrete...
