Relation isRelationForPartSpec Part Specification

This specifies the relation between whole and part that should be used
for a particular part.  For example, the relation between a company and
its president may be PresidentOf, PartOf, or whatever the user chooses.
The same relation can be used for all the parts, each part can have its
own rleation to the whole, or anything in between.  For example, a car
can have one part-whole relation pointing to all its parts, or it can
have one relation for the moving parts and another for the static parts.
