This composite change will create a value partion - see "pattern 2" in
"Representing Specified Values in OWL: "value partitions" and "value sets""
A value partition is an ontology design pattern which is used to represent a
set of closed values for a particular property. For example the property
hasSize might only take values from SmallSize, MediumSize and LargeSize. In
this case, the value partition is Size, and has the values SmallSize,
MediumSize and LargeSize. This composite change will set hasSize to be
functional and its range as Size. Size will be covered by SmallSize,
MediumSize and LargeSize and these classes which represent the values will be
made disjoint with eachother.
