Hello,
Sorry, there is support for the default PHB (see manual for addPolicyEntry,
addPolicerEntry and addPHBEntry scripting commands).
We did not add support for the Class Selector as it was outside the focus of
our studies.
This can be easy accomplished.
This will be addressed in the next release of the model.
Thanks.
