Multiplicity
The section Multiplicity in element documentation pages reports the occurence indicators of the respective element, by name the values of minOccurs and maxOccurs. For example, in <ocpRef> the multiplicity is depicted with [2..2], which means, that minOccurs=maxOccurs=2 resp., every <path> requires exactly two instances of <ocpRef>.
The default values for minOccurs and maxOccurs are 1, which means that on default an element has to be used exactly once, like in <isoCountryCode>.
As an element cannot be employed a negative number of times or halve a time, minOccurs and maxOccurs have to be non-negative integers. maxOccurs must be ≥minOccurs. maxOccurs may be unbounded (∞), as in <track>.
