You should use CQML and not PICML to specify the priorities and priority
models.  You can specify the high-level RT requirements using PICML and
then use QUICKER to transform these to CCM-specific RT policies (which you
can change if desired).  From such a CQML model, you can then generate the
RT configuration descriptors and a modified deployment plan.  I will check
in an updated BasicSP model to serve as an example under CoSMIC pretty
