A have a couple of questions regarding the MPI-2 standard.

1.  In section 8.5 is the following

	"Instead, a predefined attribute key MPI_LASTUSEDCODE is
associated with MPI_COMM_WORLD. The attribute value corresponding to
this key is the current maximum error class including the user-defined
ones."

Shouldn't "maximum error class" read "maximum error code"?


2. Why the restriction that types obtained from calls to
MPI_Type_create_f90_{real,complex,integer} cannot be freed? This
restriction doesn't appear to serve any useful purpose and the
requirement that MPI_Type_get_envelope return the precision/range used
to create such a type seems to either require an implementation to
maintain a potentially very large table or allocate dynamic storage
(which cannot be freed) to store the precision/range.


Thanks, Nick.
