  === 3.3.7 Representation for Not Applicable Dimensions ===
--Not applicable dimensions, i.e., when reported measures or attributes are not attached to those dimensions, take as value the tilde ‘’ character. This is required for datasets defined by a DSD that has the ‘evolving structure’ property set to true and that includes data from dataflows, which only use a subset of dimensions as defined by a dimension constraint. This is also required for data-related higher-level (i.e., attached to dataflow or partial list of Dimensions) reference metadata attributes that don’t have a fixed pre-defined attachment.
++Not applicable [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]], i.e., when reported [[measures>>doc:sdmx:Glossary.Measure.WebHome]] or [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] are not attached to those [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]], take as value the tilde ‘’ character. This is required for [[datasets>>doc:sdmx:Glossary.Data set.WebHome]] defined by a [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] that has the ‘evolving structure’ property set to true and that includes data from [[dataflows>>doc:sdmx:Glossary.Dataflow.WebHome]], which only use a subset of [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]] as defined by a [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] (% style="color:#e74c3c" %)constraint(%%).
