Note also that TimeDimension is constrained to specific FacetValueTypes. Moreover, the [[Representations>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of MetadataAttributes are specified in the corresponding MetadataStructureDefinition, linked by the DataStructureDefinition.

If minOccurs or maxOccurs are omitted (they both default to ‘1’), the [[Measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] is considered to take a single value; otherwise, it is an array. Moreover, the usage [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] indicates whether a [[Measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] must be reported or not, by the corresponding values: mandatory or optional.
121	121
122	122	The AttributeDescriptor may contain one or more //[[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]//s, i.e., at least one DataAttribute definition or one MetadataAttribute reference.
123	123
124		-The DataAttribute defines a characteristic of data that are collected or disseminated and is grouped in the DataStructureDefinition by a single AttributeDescriptor. The DataAttribute can be indicated if it must be reported or not, by the corresponding value of the usage [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]: i.e., mandatory or optional. The property minOccurs specifies the minimum number of array values to be included when the DataAttribute is reported. Moreover, a maxOccurs [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] indicates whether the DataAttribute may need to report more than one values, i.e., an array of values. The DataAttribute may play a specific role in the structure and this is specified by the +role association to the (% style="color:#e74c3c" %)Concept(%%) that identifies its role.
