gml:CylindricalCS is a three-dimensional coordinate system consisting of apolar coordinate system extended by a straight coordinate axis perpendicular to the planespanned by the polar coordinate system. A CylindricalCS shall have three gml:axis propertyelements.
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.
