Summary of Additions

The main addtions are:

  • MeasurementItem is a new structure modelled on QuestionItem to support Measurement

  • Survey Development (new structures to support expanded functionality)

  • Statistical Classification (new structures to support GSIM)

  • New constructs - Split and SplitJoin to support concurrent processing; DevelopmentStep, SampleStep, SamplingStage to support Survey Development and MeasurementConstruct for MeasurementItems

Summary of Changes

CodeValueType and InternationalCodeValueType have had all attribute names changed from codeListXxx to controlledVocabularyXxx. This aligns the naming with the Controlled Vocabularies published by the DDI and prevents name conflicts with the element CodeList in the DDI schemas

ComponentParts changed from type=”ComponentPartsType” to type=”LocationValueBundleType”.

ControlConstruct reference no longer supports the use of binding

DefiningConceptReference moved from conceptualcomponent.xsd to reusable.xsd
