  gml:MultiPointCoverage    In a gml:MultiPointCoverage the domain set is a gml:MultiPoint, that is a collection of arbitrarily distributed geometric points. The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiPoint. In a gml:MultiPointCoverage the mapping from the domain to the range is straightforward. - For gml:DataBlock encodings the points of the gml:MultiPoint are mapped in document order to the tuples of the data block. - For gml:CompositeValue encodings the points of the gml:MultiPoint are mapped to the members of the composite value in document order. - For gml:File encodings the points of the gml:MultiPoint are mapped to the records of the file in sequential order.
  gml:MultiCurveCoverage    In a gml:MultiCurveCoverage the domain is partioned into a collection of curves comprising a gml:MultiCurve. The coverage function then maps each curve in the collection to a value in the range set. The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiCurve. In a gml:MultiCurveCoverage the mapping from the domain to the range is straightforward. - For gml:DataBlock encodings the curves of the gml:MultiCurve are mapped in document order to the tuples of the data block. - For gml:CompositeValue encodings the curves of the gml:MultiCurve are mapped to the members of the composite value in document order. - For gml:File encodings the curves of the gml:MultiCurve are mapped to the records of the file in sequential order.
  gml:MultiSurfaceCoverage    In a gml:MultiSurfaceCoverage the domain is partioned into a collection of surfaces comprising a gml:MultiSurface. The coverage function than maps each surface in the collection to a value in the range set. The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiSurface. In a gml:MultiSurfaceCoverage the mapping from the domain to the range is straightforward. - For gml:DataBlock encodings the surfaces of the gml:MultiSurface are mapped in document order to the tuples of the data block. - For gml:CompositeValue encodings the surfaces of the gml:MultiSurface are mapped to the members of the composite value in document order. - For gml:File encodings the surfaces of the gml:MultiSurface are mapped to the records of the file in sequential order.
  gml:MultiSolidCoverage    In a gml:MultiSolidCoverage the domain is partioned into a collection of solids comprising a gml:MultiSolid. The coverage function than maps each solid in the collection to a value in the range set. The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiSolid. In a gml:MultiSolidCoverage the mapping from the domain to the range is straightforward. - For gml:DataBlock encodings the solids of the gml:MultiSolid are mapped in document order to the tuples of the data block. - For gml:CompositeValue encodings the solids of the gml:MultiSolid are mapped to the members of the composite value in document order. - For gml:File encodings the solids of the gml:MultiSolid are mapped to the records of the file in sequential order.
  gml:GridCoverage    A gml:GriddedCoverage is a discrete point coverage in which the domain set is a geometric grid of points. Note that this is the same as the gml:MultiPointCoverage except that we have a gml:Grid to describe the domain. The simple gridded coverage is not geometrically referenced and hence no geometric positions are assignable to the points in the grid. Such geometric positioning is introduced in the gml:RectifiedGridCoverage.
  gml:RectifiedGridCoverage    The gml:RectifiedGridCoverage is a discrete point coverage based on a rectified grid. It is similar to the grid coverage except that the points of the grid are geometrically referenced. The rectified grid coverage has a domain that is a gml:RectifiedGrid geometry.
  gml:FeatureCollection    deprecated
  gml:DynamicFeature    States are captured by time-stamped instances of a feature. The content model extends the standard gml:AbstractFeatureType with the gml:dynamicProperties model group. Each time-stamped instance represents a 'snapshot' of a feature. The dynamic feature classes will normally be extended to suit particular applications. A dynamic feature bears either a time stamp or a history.
  from subst. group gml:DynamicFeature
  gml:DynamicFeatureCollection    A gml:DynamicFeatureCollection is a feature collection that has a gml:validTime property (i.e. is a snapshot of the feature collection) or which has a gml:history property that contains one or more gml:AbstractTimeSlices each of which contain values of the time varying properties of the feature collection. Note that the gml:DynamicFeatureCollection may be one of the following: 1. A feature collection which consists of static feature members (members do not change in time) but which has properties of the collection object as a whole that do change in time . 2. A feature collection which consists of dynamic feature members (the members are gml:DynamicFeatures) but which also has properties of the collection as a whole that vary in time.
  gml:Observation    The content model is a straightforward extension of gml:AbstractFeatureType; it automatically has the gml:identifier, gml:description, gml:descriptionReference, gml:name, and gml:boundedBy properties. The gml:validTime element describes the time of the observation. Note that this may be a time instant or a time period. The gml:using property contains or references a description of a sensor, instrument or procedure used for the observation. The gml:target property contains or references the specimen, region or station which is the object of the observation. This property is particularly useful for remote observations, such as photographs, where a generic location property might apply to the location of the camera or the location of the field of view, and thus may be ambiguous. The gml:subject element is provided as a convenient synonym for gml:target. This is the term commonly used in phtotography. The gml:resultOf property indicates the result of the observation. The value may be inline, or a reference to a value elsewhere.
  from subst. group gml:Observation
  gml:DirectedObservation    A gml:DirectedObservation is the same as an observation except that it adds an additional gml:direction property. This is the direction in which the observation was acquired. Clearly this applies only to certain types of observations such as visual observations by people, or observations obtained from terrestrial cameras.
  from subst. group gml:DirectedObservation
  gml:DirectedObservationAtDistance    gml:DirectedObservationAtDistance adds an additional distance property. This is the distance from the observer to the subject of the observation. Clearly this applies only to certain types of observations such as visual observations by people, or observations obtained from terrestrial cameras.

  from subst. group gml:AbstractGeometricAggregate
  gml:MultiGeometry    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.
  gml:MultiPoint    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.
  gml:MultiCurve    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.
  gml:MultiSurface    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.
  gml:MultiSolid    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.
  from subst. group gml:AbstractGeometricPrimitive
  gml:Point    A Point is defined by a single coordinate tuple. The direct position of a point is specified by the pos element which is of type DirectPositionType.
  from subst. group gml:AbstractCurve
  gml:LineString    A LineString is a special curve that consists of a single segment with linear interpolation. It is defined by two or more coordinate tuples, with linear interpolation between them. The number of direct positions in the list shall be at least two.
  gml:CompositeCurve    A gml:CompositeCurve is represented by a sequence of (orientable) curves such that each curve in the sequence terminates at the start point of the subsequent curve in the list. curveMember references or contains inline one curve in the composite curve. The curves are contiguous, the collection of curves is ordered. Therefore, if provided, the aggregationType attribute shall have the value "sequence".
  gml:Curve    A curve is a 1-dimensional primitive. Curves are continuous, connected, and have a measurable length in terms of the coordinate system. A curve is composed of one or more curve segments. Each curve segment within a curve may be defined using a different interpolation method. The curve segments are connected to one another, with the end point of each segment except the last being the start point of the next segment in the segment list. The orientation of the curve is positive. The element segments encapsulates the segments of the curve.
  gml:OrientableCurve    OrientableCurve consists of a curve and an orientation. If the orientation is "+", then the OrientableCurve is identical to the baseCurve. If the orientation is "-", then the OrientableCurve is related to another AbstractCurve with a parameterization that reverses the sense of the curve traversal.
  from subst. group gml:AbstractSurface
  gml:Polygon    A Polygon is a special surface that is defined by a single surface patch (see D.3.6). The boundary of this patch is coplanar and the polygon uses planar interpolation in its interior. The elements exterior and interior describe the surface boundary of the polygon.
  gml:CompositeSurface    A gml:CompositeSurface is represented by a set of orientable surfaces. It is geometry type with all the geometric properties of a (primitive) surface. Essentially, a composite surface is a collection of surfaces that join in pairs on common boundary curves and which, when considered as a whole, form a single surface. surfaceMember references or contains inline one surface in the composite surface. The surfaces are contiguous.
  gml:Surface    A Surface is a 2-dimensional primitive and is composed of one or more surface patches as specified in ISO 19107:2003, 6.3.17.1. The surface patches are connected to one another. patches encapsulates the patches of the surface.
  from subst. group gml:Surface
  gml:PolyhedralSurface    A polyhedral surface is a surface composed of polygon patches connected along their common boundary curves. This differs from the surface type only in the restriction on the types of surface patches acceptable. polygonPatches encapsulates the polygon patches of the polyhedral surface.
  gml:TriangulatedSurface    A triangulated surface is a polyhedral surface that is composed only of triangles. There is no restriction on how the triangulation is derived. trianglePatches encapsulates the triangles of the triangulated surface.
  from subst. group gml:TriangulatedSurface
  gml:Tin    A tin is a triangulated surface that uses the Delauny algorithm or a similar algorithm complemented with consideration of stoplines (stopLines), breaklines (breakLines), and maximum length of triangle sides (maxLength). controlPoint shall contain a set of the positions (three or more) used as posts for this TIN (corners of the triangles in the TIN). See ISO 19107:2003, 6.4.39 for details.
  gml:OrientableSurface    OrientableSurface consists of a surface and an orientation. If the orientation is "+", then the OrientableSurface is identical to the baseSurface. If the orientation is "-", then the OrientableSurface is a reference to a gml:AbstractSurface with an up-normal that reverses the direction for this OrientableSurface, the sense of "the top of the surface".
  from subst. group gml:AbstractSolid
  gml:CompositeSolid    gml:CompositeSolid implements ISO 19107 GM_CompositeSolid (see ISO 19107:2003, 6.6.7) as specified in D.2.3.6. A gml:CompositeSolid is represented by a set of orientable surfaces. It is a geometry type with all the geometric properties of a (primitive) solid. Essentially, a composite solid is a collection of solids that join in pairs on common boundary surfaces and which, when considered as a whole, form a single solid. solidMember references or contains one solid in the composite solid. The solids are contiguous.
  gml:Solid    A solid is the basis for 3-dimensional geometry. The extent of a solid is defined by the boundary surfaces as specified in ISO 19107:2003, 6.3.18. exterior specifies the outer boundary, interior the inner boundary of the solid.
  gml:GeometricComplex    
  from subst. group gml:AbstractImplicitGeometry
  gml:Grid    The gml:Grid implicitly defines an unrectified grid, which is a network composed of two or more sets of curves in which the members of each set intersect the members of the other sets in an algorithmic way. The region of interest within the grid is given in terms of its gml:limits, being the grid coordinates of diagonally opposed corners of a rectangular region. gml:axisLabels is provided with a list of labels of the axes of the grid (gml:axisName has been deprecated). gml:dimension specifies the dimension of the grid. The gml:limits element contains a single gml:GridEnvelope. The gml:low and gml:high property elements of the envelope are each integerLists, which are coordinate tuples, the coordinates being measured as offsets from the origin of the grid along each axis, of the diagonally opposing corners of a "rectangular" region of interest.
  from subst. group gml:Grid
  gml:RectifiedGrid    A rectified grid is a grid for which there is an affine transformation between the grid coordinates and the coordinates of an external coordinate reference system. It is defined by specifying the position (in some geometric space) of the grid "origin" and of the vectors that specify the post locations. Note that the grid limits (post indexes) and axis name properties are inherited from gml:GridType and that gml:RectifiedGrid adds a gml:origin property (contains or references a gml:Point) and a set of gml:offsetVector properties.
