                             Generic: Child type parameters  | 
                        
                             In a navigable association, if the parent is generic, the child must redefine all the type parameters of the parent. If the parent is a partially bound classifier (where some type parameters are not resolved) then the child must redefine all the unresolved type parameters. Manual correction: Resolve the missing type parameters. Automatic correction: None.  |

                             Generic: Child cannot be bound  | 
                        
                             A bound classifier cannot be the child of any navigable association other than its generic parent. Manual correction: Remove the additional links. Automatic correction: None.  |
