  **Multi-value measures and attributes**
++Both measures and attributes have been extended with the option to take ‘arrays’ of 193 multiple coded or uncoded values. This supports use cases like multiple observation 194 status flags. New //minOccurs// and //maxOccurs// properties define the valid number of 195 values. The //usage// property separately defines whether the measure or attribute is //mandatory// or optional. In the SDMX-ML measure example above, the properties //minOccurs=”1” maxOccurs=”1” usage=”mandatory”// specify that OBS_VALUE must be 198 reported, and can only consist of a single value.

  **Attributes relationship to measures**
--In addition to attaching [[attributes>>doc:xwiki:Glossary.Attribute.WebHome]] to a specific (% style="color:#2ecc71" %)level(%%) within the [[dataset>>doc:xwiki:Glossary.Data set.WebHome]], their relationship 202 to [[measures>>doc:xwiki:Glossary.Measure.WebHome]] can also be defined.

  (% class="wikigeneratedid" id="HValuelists" %)
  **Value lists**
--Value lists help in modelling microdata by providing an enumeration similar to [[code lists>>doc:xwiki:Glossary.Code list.WebHome]] 206 but allowing any string values without being restricted to the rules of [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] identifiers. That allows ValueItems (the equivalent to [[Code>>doc:xwiki:Glossary.Code.WebHome]]) to contain symbols like ‘¥’ and ‘€’, but also means they are not identifiable.

  (% class="wikigeneratedid" id="HGeospatialInformationtype" %)
  **GeospatialInformation type**
--A new GeospatialInformation string type has been added which can be used as the [[representation>>doc:xwiki:Glossary.Representation.WebHome]] for any [[dimension>>doc:xwiki:Glossary.Dimension.WebHome]], [[attribute>>doc:xwiki:Glossary.Attribute.WebHome]] or measure [[component>>doc:xwiki:Glossary.Component.WebHome]]. The value which is a string expression conforming to the syntax defined in Section 6 of the technical specifications precisely defines a ‘Geo Feature Set’ – a collection of geographical features like points, lines or polygons. Its use is recommended in conjunction with the “GEO_FEATURE_SET” (% style="color:#2ecc71" %)concept(%%) role.
++A new GeospatialInformation string type has been added which can be used as the 214 representation for any dimension, attribute or measure component. The value which is a 215 string expression conforming to the syntax defined in Section 6 of the technical 216 specifications precisely defines a ‘Geo Feature Set’ – a collection of geographical 217 features like points, lines or polygons. Its use is recommended in conjunction with the “GEO_FEATURE_SET” concept role.

  **Geospatial code lists**
++Two new specialised types of code list have been added where the definition of each code includes additional geospatial information in addition to the standard ID, name and description:

  * GeographicCodelist – each item includes an element to represent a specific Geo Feature Set which is described using the same expression syntax as for GeospatialInformation type.
--* GeoGridCodelist – A [[code list>>doc:xwiki:Glossary.Code list.WebHome]] defining a geographical grid composed of cells representing regular squared portions of the Earth. Each item references a cell within the grid.
