gml:Ring 

A ring is used to represent a single connected component of a surface boundary as specified in ISO 19107:2003, 6.3.6.
Every gml:curveMember references or contains one curve, i.e. any element which is substitutable for gml:AbstractCurve. In the context of a ring, the curves describe the boundary of the surface. The sequence of curves shall be contiguous and connected in a cycle.
If provided, the aggregationType attribute shall have the value "sequence".
