Subject: [eman] AC vs DC and # of phases

There are two requirements that are related:

  5.2.7.  Type Of current

   The standard must provide means for reporting the type of current (AC
   or DC) for each Power Interface as well as for a device.

    5.2.10.  Number Of AC Phases

   The standard must provide means for reporting the number of AC phases
   for each Power Interface.

  The first is presumably only AC or DC and the second 1-phase or 3-phase.
It seems for implementation purposes these could be combined into a
single value of DC, 1-phase AC, 3-phase AC delta, or 3-phase AC wye.
I assume the framework could specify this and be consistent with the
two requirements.
