Good points. I'm also a little uncomfortable with just 32 attributes

There are situations in standardization where deciding 32 bits is enough leads to very costly retrofit down the road because the implications of the decision become pervasive. IP addresses is a good example. In this case, the cost of being too conservative is that some day the MPI 6.0 Forum (which I hope not to be working on) will need to define a new MPI_Init call and deprecate the one that supports only 32 or 64 assertions. I am hopeful that we will never go beyond a dozen of so assertions.
