Shouldn't there be a bit more discussion of the file pointer
types here (shared vs. independent) and how they are updated,
or at least a reference to that information elsewhere?
You describe the buftypes pretty carefully but say nothing
about filetypes. I assume that's because it's described in
under Views. There should be a reference to that as well.

This sentence is still very misleading. You should say
explicitly that you get the count of etypes and buftypes
from MPI_Get_count (either directly or by doing the math yourself,
whatever we decide), and you get the number of basic types from
MPI_Get_elements.
