			A property with the content model of gml:AbstractRingPropertyType encapsulates a ring to represent the surface boundary property of a surface.
		
		
			
		
	
	
		
			A boundary of a surface consists of a number of rings. In the normal 2D case, one of these rings is distinguished as being the exterior boundary. In a general manifold this is not always possible, in which case all boundaries shall be listed as interior boundaries, and the exterior will be empty.
		
	
	
		
			A boundary of a surface consists of a number of rings. The "interior" rings separate the surface / surface patch from the area enclosed by the rings.
		
	
	
	
		
			
				
					
						
					
				
			
		
	
	
	
		
			gml:SurfaceArrayPropertyType is a container for an array of surfaces. The elements are always contained in the array property, referencing geometry elements or arrays of geometry elements via XLinks is not supported.
		
		
			
		
	
	
	
		
			A property that has a surface 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 LinearRing is defined by four or more coordinate tuples, with linear interpolation between them; the first and last coordinates shall be coincident. The number of direct positions in the list shall be at least four.
		
	
	
		
			An abstraction of a ring to support surface boundaries of different complexity.
The AbstractRing element is the abstract head of the substituition group for all closed boundaries of a surface patch.
		
	
	
	
		
			gml:AbstractSurfaceType is an abstraction of a surface to support the different levels of complexity. A surface is always a continuous region of a plane.
		
		
	
	
	
		
	
	
		
			The AbstractSurface element is the abstract head of the substitution group for all (continuous) surface elements.
