Multiplicity (M)

In the Specification tables M refers to the number of instances or occurrences of an element or attribute that are allowed or required in a given context. It defines how many times a particular component (element or attribute) can appear within a specific structure.

M	Definition
1	The element or attribute must be present exactly once.
0..1	The element or attribute is optional; it can be present zero or one time.
0..n	The element or attribute can be present zero or more times, with no upper limit (where n represents an infinite number of occurrences).
1..n	The element or attribute must be present at least once and can be present any number of times, with no upper limit.
n..m	Specific range, the element or attribute must be present at least n times and no more than m times (where n and m are specific numbers).
