This is the XML structure, defined in QTI, that represents the question presented in an online test. The term 'Item' is used because the corresponding XML-instance contain more than just the information to present the question to the learner. It also includes: the response processing to determine if the answer is correct or not; the set of scores to be assigned to the learner and the rules for aggregating these scores; the alternative information to be rendered according to the accessibility needs and preferences of the learner; information to be presented as a hint.
