Definition: 

A sub-universe group provides a definition to the universes contained within it.

Explanatory Notes: 

In addition to the standard name, label, and description, the SubUniverseClass references a concept which defines it, and references to the universes and or other sub-universe groups it contains. The contents of the SubUniverseClass may be designated as ordered.

The value of a hierarchical structure is understanding the relationships of objects within each hierarchical structure. So the SubUniverseClass may be defined as family/household relationships where the universes are Father, Mother, Adolescent, (other groups within the family or household could also be defined for completeness or a simple clarification that the SubUniverse was not exhaustive in coverage).

Other hierarchies (defining other SubUniverseClasses like income, education or work status,) could also be defined. The study would point to the overall population and each question in each questionnaire would point to at least one of the SubUniverseClass universes defined within family/household relationships plus any additionally defining universe.

Example: 
For example the Sub-Universe Group of Gender for the Universe Resident Population may contain the Universe Males and the Universe Females.
Property:

name
0..n
A name for the SubUniverseClass. May be expressed in multiple languages. Repeat the element to express names with different content, for example different names for different systems.
label
0..n
A display label for the SubUniverseClass. May be expressed in multiple languages. Repeat for labels with different content, for example, labels with differing length limitations.
description
0..1
A description of the content and purpose of the SubUniverseClass.
isOrdered
0..1
If set to "true" indicates that the content of the group is ordered as it appears within the XML structure.

definingConcept
A concept that provides a grouping factor for the universes contained by the SubUniverseClass. For example if the parent Universe is Population of the World and the two universes in the group are Male and Female the defining concept may be Sex.

Neither
belongsToUniverse
A reference to a universe contained in this SubUniverseClass. Note that two different parent universes may contain references to the same universe within a sub-universe group. For example, the Universe "Population of Europe" and the Universe "Population of the United States" may both have a reference to the SubUniverseClass with the defining concept of Gender and member Universes "Males" and "Females". The SubUniverseClass is ALWAYS a restriction of its parent universe so that in one case it would be "Males within the Population of Europe" and in the other usage "Males within the Population of the United States". A question or variable should reference each relevant universe to define the appropriate intersect group.
