+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.

+
+
+
+
+
+
+
+
+
+
+
+
+
+ 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.
