ComputationItemType (as extension base),

IfThenElseType (as extension base),

LoopType (as extension base),

QuestionConstructType (as extension base),

RepeatUntilType (as extension base),

RepeatWhileType (as extension base),

As direct type of elements (1):
ControlConstruct

Annotation

Provides the basic, extensible structure for control elements used in describing flow logic within the instrument. The only data point which is inherited by the extended constructs based on this type is the identification of the control construct.

ExternalAid

Type:

r:OtherMaterialType, complex content

A pointer to an exteral aid presented by the instrument such as a text card, image, audio, or audiovisual aid. Typically a URN. Use type attribute to describe the type of external aid provided. Example of terms to use would include: imageOnly audioOnly audioVisual multiMedia. ExternalAid will be be available each time the control construct is invoked. Care should be taken when placing an ExternalAid in RepeatWhile, RepeatUntil and Loop constructs as it will recure each time the conditional statement is checked. This does not include interviewer instructions, which are handled separately.
