[regrep-comment] Add ability to add ClassificationSlots ?

[John Silva <johns@anr.ms.philips.com>]

In ebXML reg/rep right now if I have a named metadata item that I use a
with a
Classification Scheme, there is no way for me to give that multiple values.
Imagine that I had a metadata item named  shape that could take multiple
values from a Classification
Scheme; e.g. the shape square is a square, rhombus, parallelogram, and
quadrangle (not a good
example but you get the idea).   How could this be represented in ebXML
(besides a Slot) ?   Another idea,
maybe related to the idea of multiple inheritance of Classifications,
what if Classifications could
be represented like Slots, i.e. as a ValueList:

     <ClassificationSlot name=shape>
         <ValueList>
              <Value scheme="ShapeScheme">square</Value>
              <Value scheme="ShapeScheme">rhombus</Value>
              <Value scheme="ShapeScheme">parallelogram</Value>
              <Value scheme="ShapeScheme">quadrangle</Value>
              <Value scheme="PrimaryColors">red</Value>
              <Value scheme="FillType">solid</Value>
          </ValueList>
     </ClassificationSlot>

Thanks,
