Provides a set of constants that specify whether a property can hold a single value (single cardinality) or a
collection of multiple values (list or enumeration cardinality).

ENUM |
Specifies a property with enumeration cardinality. A property with enumeration cardinality is an object-valued property
that returns a set collection. A set collection is a read-only collection of unique, unordered, independent objects that must
be traversed sequentially. You can iterate through the items of a set collection one page of elements at a time from the server to your
client application. However, if the collection changes on the server while you are iterating through it, the number, order, and values
of the items in your client copy can change, even if you maintain the same reference to it. A set collection cannot hold any items
other than independent objects. By contrast, a list collection can hold items of any data type, with the exception of independent objects.

SINGLE |
Specifies a property with single cardinality. A property with single cardinality returns a single value of the
data type that the property can hold.
| |
LIST |
Specifies a property with list cardinality. A property with list cardinality returns a list collection. A list collection is a collection
of ordered items that can either be modifiable (allowing items to be inserted, replaced, or deleted) or read-only. These items
need not be unique and can be traversed in any order. When you access a list collection from the server, a complete copy of it
is created on your client application, which you can iterate through one element at a time. The items in a list collection must all be
of the same data type and must match the data type of the property that returns it. If the property returning a list collection is an
object-valued property, all of the objects in the list collection must be dependent objects. A list collection can hold items of any
data type (provided each item is of the same data type. However, if a list collection holds objects, they must all be dependent objects;
only a set collection can hold independent objects. You cannot create a custom property with list cardinality.
