*_dut params for waveform tables

IBISgurus,

For waveform tables, there are sub-params called R_dut, L_dut and C_dut. These
are same as R_pkg, L_pkg and C_pkg. From talking to a few IBIS experts I
understand that waveform tables should be generated without any pkg parasitics.
Simulators will attach the package parasitcs to the waveform tables and
run simulations.

That means, do not include *_dut in your s2ibis2 translation. If that is true,
 
Why does s2ibis2 include R_d, L_d and C_d parameters ?
Why does IBIS even have *_dut parameters in the spec ?
How does one avoid double counting of pkg numbers for V/T ?

Are the *_dut only for measurement based IBIS models ?
