    When the minimum value is zero, the specified element is not required; the element is optional.

    1

    The specified element must occur at least once.

  • maxOccurs
    Optional. The maximum number of times the element can occur on the element. The following values can be assigned to this attribute.

ElementType, group

Child elements

Remarks

ElementType declarations can constrain the content and attributes that appear in elements of the named type by referring to other element type or attribute type declarations.

The minOccurs and maxOccurs attributes have the default value 1. An element with neither attribute specified uses these default values and therefore must appear once and only once in a content model.
