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 is an OGC Standard.

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.
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.
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.
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.
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.
