 Message        <Context> "<name>" is a builtin and cannot be used in
                this context.

 Description    A program has used a builtin function in a way that
                is invalid for builtin functions.  For example, a
                program cannot take the address of a builtin.

 User Action    Remove the improper use of the builtin.
