DATA MODEL BUILDING MODES
=========================
This section helps construct the ResponseML data model used to capture responses.
Starting from the instrument dataBuilder template, which works on a DDI instrument, it iteratively builds a explict tree based on the implicit DDI hierarchy for a questionnaire.
For more information on the ResponseML format view the doccumentation for ResponseML.
The algorithm for this transform works as so:
1. Find a DDI instrument
a. From the instrument get the reference to the ControlConstruct (Sequence, IfThenElse, Loop, QuestionConstruct)
2. Find the reference ControlConstruct
3. For the given ControlConstruct in step 2, and if it is a...
a. QuestionConstruct, output a <rml:response> element.
b. Sequence, output a <rml:sequence>, then get all references to child ControlConstructs and process them, preserving document order, from step 2 as children of the new element.
c. IfThenElse, get the Then and option Else references, and create a <rml:then> or <rml:else> element, process them, preserving document order, from step 2 as children of the appropriate then or else element.

The default transform for this style sheet will find all DDI Instruments and create the appropriate ResponseML data model from them.
