Next in thread: Steve Huss-Lederman: "Re: new version of chapter"

Attached is a new version of the external interfaces chapter. It is a
copy of the one included in the full document released today. Its
difference form the previous version are:

- the new proposal for a character representation of a datatype is
included.

- a proposal for support for layered products

- a more detailed second proposal for MPI_Datatype
