See ISO/DIS 19136 12.3.
Geometric aggregates (i.e. instances of a subtype of gml:AbstractGeometricAggregateType) are arbitrary aggregations of geometry elements. They are not assumed to have any additional internal structure and are used to "collect" pieces of geometry of a specified type. Application schemas may use aggregates for features that use multiple geometric objects in their representations.
gml:AbstractGeometricAggregate is the abstract head of the substitution group for all geometric aggregates.
gml:MultiGeometry is a collection of one or more GML geometry objects of arbitrary type.
The members of the geometric aggregate may be specified either using the "standard" property (gml:geometryMember) or the array property (gml:geometryMembers). It is also valid to use both the "standard" and the array properties in the same collection.
This property element either references a geometry element via the XLink-attributes or contains the geometry element.
This property element contains a list of geometry elements. The order of the elements is significant and shall be preserved when processing the array.
A property that has a geometric aggregate as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere in the same document). Either the reference or the contained element shall be given, but neither both nor none.
This property element either references a geometric aggregate via the XLink-attributes or contains the "multi geometry" element. multiGeometryProperty is the predefined property, which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for AbstractGeometricAggregate.
A gml:MultiPoint consists of one or more gml:Points.
The members of the geometric aggregate may be specified either using the "standard" property (gml:pointMember) or the array property (gml:pointMembers). It is also valid to use both the "standard" and the array properties in the same collection.
This property element either references a Point via the XLink-attributes or contains the Point element.
This property element contains a list of points. The order of the elements is significant and shall be preserved when processing the array.
A property that has a collection of points as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere in the same document). Either the reference or the contained element shall be given, but neither both nor none.
This property element either references a point aggregate via the XLink-attributes or contains the "multi point" element. multiPointProperty is the predefined property, which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for MultiPoint.
A gml:MultiCurve is defined by one or more gml:AbstractCurves.
The members of the geometric aggregate may be specified either using the "standard" property (gml:curveMember) or the array property (gml:curveMembers). It is also valid to use both the "standard" and the array properties in the same collection.
This property element contains a list of curves. The order of the elements is significant and shall be preserved when processing the array.
A property that has a collection of curves as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere in the same document). Either the reference or the contained element shall be given, but neither both nor none.
This property element either references a curve aggregate via the XLink-attributes or contains the "multi curve" element. multiCurveProperty is the predefined property, which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for MultiCurve.
A gml:MultiSurface is defined by one or more gml:AbstractSurfaces.
The members of the geometric aggregate may be specified either using the "standard" property (gml:surfaceMember) or the array property (gml:surfaceMembers). It is also valid to use both the "standard" and the array properties in the same collection.
This property element contains a list of surfaces. The order of the elements is significant and shall be preserved when processing the array.
A property that has a collection of surfaces as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere in the same document). Either the reference or the contained element shall be given, but neither both nor none.
This property element either references a surface aggregate via the XLink-attributes or contains the "multi surface" element. multiSurfaceProperty is the predefined property, which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for MultiSurface.
A gml:MultiSolid is defined by one or more gml:AbstractSolids.
The members of the geometric aggregate may be specified either using the "standard" property (gml:solidMember) or the array property (gml:solidMembers). It is also valid to use both the "standard" and the array properties in the same collection.
This property element either references a solid via the XLink-attributes or contains the solid element. A solid element is any element, which is substitutable for gml:AbstractSolid.
This property element contains a list of solids. The order of the elements is significant and shall be preserved when processing the array.
A property that has a collection of solids as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere in the same document). Either the reference or the contained element shall be given, but neither both nor none.
This property element either references a solid aggregate via the XLink-attributes or contains the "multi solid" element. multiSolidProperty is the predefined property, which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for MultiSolid.
