Such axes include the Longitude and Latitude of Ellipsoidal and Spherical coordinate systems. That geometry could lie within a small region on the surface of the ellipsoid or sphere, or could extend completely around the ellipsoid or sphere.

10.2 Abstract geometric primitives

10.2.1 AbstractGeometricPrimitiveType, AbstractGeometricPrimitive

complexType name=AbstractGeometricPrimitiveType abstract=true complexContent extension base=gml:AbstractGeometryType complexContent complexType element name=AbstractGeometricPrimitive type=gml:AbstractGeometricPrimitiveType abstract=true substitutionGroup=gml:AbstractGeometry gml:AbstractGeometricPrimitiveType is the abstract root type of the geometric primitives. A geometric primitive is a geometric object that is not decomposed further into other primitives in the system. All primitives are oriented in the direction implied by the sequence of their coordinate tuples. The gml:AbstractGeometricPrimitive element is the abstract head of the substitution group for all pre- and user-defined geometric primitives. gml:AbstractGeometricPrimitive implements ISO 19107 GM_Primitive see D.2.3.3 and ISO 19107:2003, 6.3.10.

10.2.2 GeometricPrimitivePropertyType

complexType name=GeometricPrimitivePropertyType sequence minOccurs=0 element ref=gml:AbstractGeometricPrimitive sequence attributeGroup ref=gml:OwnershipAttributeGroup attributeGroup ref=gml:AssociationAttributeGroup complexType A property that has a geometric primitive 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.
