Our intent was to list the capabilities that we could agree would come
from these assumptions.  It was not intended as a complete list.  

Once we have the assumptions vetted, then we hope to do an update of the
document where we then would do a complete job of listing the
capabilities needed for DCL.

If there are any obvious capabilities missing today, we would be happy
to add them, but given our approach, it isnt necessary to have them
