Motion P1788/M0002.01_ProcessStructure NO
I vote NO on motion 2.
Rationale:
In an interval standard, the opportunity exists to leave open how
intervals are represented, thereby requiring *only* that the
mathematical interpretation of any representation must not violate the
containment constraint of interval arithmetic. This in turn forces the
standard to answer only the more fundamental question: For a given set
of (bounded, or unbounded) intervals, what is the set of values is that
must be contained in the interval result of any interval computation?
To do anything more than this risks stifling innovations that might
result in ways to automate (in hardware or software) fast ways to
compute narrow width interval bounds.
Modal intervals are just one of many possible innovations.
