104 104  There are three types of dimension each having a common association to Concept:
105 105  
106 106  * Dimension
107 -* MeasureDimension
108 -* TimeDimension
107 +* MeasureDimension  TimeDimension

110 110  Note that In the description here //DimensionComponent// can be oany or all of its sub classes i.e. Dimension, MeasureDimension, TimeDimension., and the term “DataAttribute” refers to both DataAttribute and its sub class ReportingYearStartDate.
111 111  
112 112  The //DimensionComponent//, DataAttribute, and PrimaryMeasure link to the Concept that defines its name and semantic (/conceptIdentity association to Concept). The DataAttribute, Dimension, and MeasureDimension (but not TimeDimension) can optionally have a +conceptRole association with a Concept that identifies its role in the DataStructureDefinition. Therefore, the allowable roles of a Concept are maintained in a ConceptScheme. Examples of roles are: geography, entity, count, unit of measure. The use of these roles is to enable applications to process the data in a meaningful way (e.g. relating a dimension value to a mapping vector). It is expected that communities (such as the official statistics community) will harmonise these roles with their community so that data can be exchanged and shared in a meaningful way in the community.

114 -The valid values for a //DimensionComponent//, PrimaryMeasure, or DataAttribute, when used in this DataStructureDefinition, are defined by the Representation. This Representation is taken from the Concept definition (coreRepresentation) unless it is overridden in this DataStructureDefinition (localRepresentation) – see Figure 23. Note that for the MeasureDimension the Representation must be a ConceptScheme and this must always be referenced from the MeasureDimension and cannot therefore be defaulted to the Representation of the Concept associated by the/conceptIdentity. Note also that TimeDimension and ReportingYearStartDate are constrained to specific FacetValueTypes
