Question

Quizplus · Accepted Answer

Choice A has the correct syntax for declaring an attribute, with the attribute name "semester," the allowed values "fall," "spring," or "summer," and the requirement for the attribute to be present (#REQUIRED). Choice B is incorrect because the allowed values should be separated by vertical bars, not commas. Choices C and D are incorrect because they attempt to declare an attribute for the element "semester," when the attribute is actually for the element "course."
