Two things.

(1) I seem to recall that the PAR mentions "dependable computing"
    as well as "Interval Arithmetic", and

(2) didn't Motion 9 -- which passed -- require inclusion of Exact Dot Product?

So it has to mentioned somewhere.  But it is definitely a Level 2 issue,
because at Level 1 everything is Exact (if it is defined at all).  Perhaps
a Note with a forwards reference?
