For any attribute which has as its domain wname or ename, if an application attempts to assign (via a command) a value for the attribute which does not identify a window or element which exists at the conclusion of that command, an error condition occurs with $ECODE containing ",M?3," and $EREF containing a value that indicates the ssvn reference to which the application attempted to assign the invalid wname or ename. Subsequent destruction of the window or element does not cause an error condition to occur.
