This function returns the minCard and maxCard of a certain
property in the context of a class. The cardinality of a property in
an instance has to be between minCard and maxCard (as well as within the cardinality restrictions
as given by the property in context of any of its (indirect) parent classes).
If undefined minCard and/or maxCard will be of value -1, this means
for minCard that it is 0 and for maxCard it means infinity.
Note: this function does not return inherited restrictions. The example shows how to retrieve
this knowledge, as it is derived knowledge the call that used to be available is removed.

Property owlClass
Size: 64 bit / 8 byte (value)
This attribute represents a handle to the class. The term owl is comming from W3C, the classes follow the expression power of Semantic Web concepts, therefore classes support multiple inheritance. Technically classes can also be distributed over different resources, however for this the parametric library is required as an extension on the basic Geometry Kernel API.
Property rdfProperty
Size: 64 bit / 8 byte (value)
This attribute represents a handle to the property, this can be either a datatype property (attribute), an object property (relation) or non-defined property. The handle will be static during the life-time of the model, when the model (or part of it) is saved and opened again, the handle will most probably be different.
Property minCard
Size: 32 bit / 4 byte (reference)
The minimum cardinality (i.e. number of elements) of this property.
Property maxCard
Size: 32 bit / 4 byte (reference)
The maximum cardinality (i.e. number of elements) of this property.
