Definition
The cardinality of a node is an abbreviation for "collection cardinality of a node". It defines the minimum and maximum number of elements (values) that the collection of a node must or can have.
The following four combinations are possible:
- 0..1
- 1..1
- 0..n
- 1..n
The first value specifies whether the collection can be empty (0..x) or cannot be empty (1..x). The second value specifies whether the node implements a collection semantics (x..n) or a singleton semantics (x..1).
