This complex type is expected to be used or extended for all applicable operation methods, without defining operation-method-specialized element names.The generalOperationParameter elements are an unordered list of associations to the set of operation parameters that are members of this group.
The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.
