Attributes

maxOccurs

The xs:choice element specifies that any one of the definitions included inside it (xs:element, xs:group, xs:choice, xs:sequence, or xs:any) may appear. When the xs:choice element is used outside an xs:group element, the maxOccurs and minOccurs attributes may set the number of times this choice can happen. The default is 1, but it can be set higher—even to unbounded—allowing the creation of elements that contain an arbitrary number of mixed elements.
