class instanceThe "_Curve" element is the abstract head of the substituition group for all (continuous) curve elements.
class instanceThe "_CurveSegment" element is the abstract head of the substituition group for all curve segment elements, i.e. continuous segments of the same interpolation mechanism.
class instanceThe "_GeometricPrimitive" element is the abstract head of the substituition group for all (pre- and user-defined)
geometric primitives.
class instanceThe "_Geometry" element is the abstract head of the substituition group for all geometry elements of GML 3. This
includes pre-defined and user-defined geometry elements. Any geometry element must be a direct or indirect extension/restriction
of AbstractGeometryType and must be directly or indirectly in the substitution group of "_Geometry".
class instanceGlobal element which acts as the head of a substitution group that may include any element which is a GML feature, object, geometry or complex value
class instanceThis abstract element is the head of a substitutionGroup hierararchy which may contain either simpleContent or complexContent elements. It is used to assert the model position of "class" elements declared in other GML schemas.
class instanceThe "_Ring" element is the abstract head of the substituition group for all closed boundaries of a surface patch.
class instanceThe "_Surface" element is the abstract head of the substituition group for all (continuous) surface elements.
