Quizplus · Accepted Answer

The most appropriate way to indicate these restrictions is by using the minOccurs and maxOccurs attributes in the element declaration. Setting the value of minOccurs to 1 indicates that the element must appear at least once, while setting maxOccurs to 20 indicates that the element can appear at most 20 times. Choice A is incorrect as the occurs attribute is not a valid attribute for element declarations. Choice B is also incorrect as the brackets and colon syntax is used for specifying ranges for attribute values, not occurrence constraints for elements. Choice C is incorrect as the use attribute is used for indicating whether a complex type definition is being re-used, and not for occurrence constraints.
