             A group may be used to aggregate arbitrary CityObjects according to some user-defined criteria. Examples for groups are the
                buildings in a specific region, the result of a query, or objects put together for visualization purposes. Each group has a name (inherited from
                AbstractGMLType), functions (e.g., building group), a class and zero or more usages. A geometry may optionally be attached to a group, if the
                geometry of the whole group differs from the geometry of the parts. Each member of a group may be qualified by a role name, reflecting the role
                each CityObject plays in the context of the group. As subclass of _CityObject, a CityObjectGroup inherits all attributes and relations, in
                particular an id, names, external references, and generalization relations. As CityObjectGroup itself is a CityObject, it may also be contained
                by another group. 
        
        
            
                
                    
                    
                    
                    
                    
                    
                    
                
            
        
    
    
    
    
    
    
    
    
    
        
            Denotes the relation of a CityObjectGroup to its members, which are _CityObjects. The CityObjectGroupMemberType element must
                either carry a reference to a _CityObject object or contain a _CityObject object inline, but neither both nor none. 
        
        
            
            
        
        
        
    
    
    
    
    
        
            Denotes the relation of a CityObjectGroup to its parent, which is a CityObject. The CityObjectGroupParentType element must either
                carry a reference to a _CityObject object or contain a _CityObject object inline, but neither both nor none. The parent association allows for
                modelling of a generic hierarchical grouping concept. Named aggregations of components (CityObjects) can be added to specific CityObjects
                considered as the parent object. The parent association links to the aggregate, while the parts are given by the group members.
