A gml:CompositeSurface is represented by a set of orientable surfaces. It isgeometry type with all the geometric properties of a (primitive) surface. Essentially, acomposite surface is a collection of surfaces that join in pairs on common boundary curvesand which, when considered as a whole, form a single surface. surfaceMember references orcontains inline one surface in the composite surface. The surfaces arecontiguous.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
