            Some error messages need to contain references to runtime-dependent data (say, the
            name of a concrete table in the database), which in the resource file's strings are
            represented by a placeholder, namely $1$, $2, and so on. This method allows to
            retrieve such an error message, and replace upo to 3 placeholders with their concrete
            values.

            In a non-product build, assertions will fire if the number of placeholders in the
            message's resource string does not match the number of passed parameter values.

                will happen, and <code>_rParamValue2</code> and <code>_rParamValue3</code> will be
                ignored.
