Hot Text Interaction (QTI)
The hottext interaction presents a set of choices to the candidate represented as selectable runs of text embedded within a surrounding context, such as a simple passage of text. Like choiceInteraction, the candidate’s task is to select one or more of the choices, up to a maximum of maxChoices. The interaction is initialized from the defaultValue of the associated response variable, a NULL value indicating that no choices are selected (the usual case). The hottextInteraction must be bound to a response variable with a baseType of identifier and single or multiple cardinality. The relevant classes are:

Examples
This example illustrates the hottextInteraction. This interaction presents a passage of text with some hot words/phrases highlighted and selectable by the candidate. It differs from the choiceInteraction in that the choices have to be presented in the context of the surrounding text.
