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).
