Notes:

1. DQ_Element is an abstract class. It has to be instantiated through one of its concrete subclasses. The appropriate subclass depends on the quality criteria concerned by the quality measure. For the unspecified quality report, the value of RSUQR.qualityElement has to be used to declare the concrete subclass used (for exemple DQ_CompletenessOmission shall be used instead of DQ_Element, the default one is DQ_ConceptualConsistency). For regulated quality, the registered measures precise which data quality element is to be used.

2. Units of measures are implemented in the ISO metadata by reference to a unit of measure register. The URL of the reference can be derived from the codelist value of the DMF Property. See Additional Instructions

3. In DMF, the measure applies to the extent of the data so the "extent" element should not be instanciated.

4. There shall be one or two results. When there are two, there shall be at least one conformance result.
