Editing CDF parameter properties for a Pcell

 The only documentation on this I have found is from Cadence Design Framework II SKILL Functions Reference (skdref.pdf) on page 698:

Attribute     Set?  Type   Description

valueType   no     string  The type of the value of this property:
                                     “boolean” Boolean
                                     “fileName” file name string
                                     “float” Floating-point integer
                                     “hierProp” Property list
                                     “ILExpr” IL expression string
                                     “ILList” IL list
                                     “int” Integer
                                     “NLPExpr” NLP expression string
                                     “string” String
                                     “time” Time-valued string

I want to be able to force the display name or prompt of pcell parameters by editing the pcell's base cdf:

cdfCreateParam(cdfCreateBaseCellCDF(ddGetObj(libName cellName))
    ?name            "myParam"
    ?prompt          "My Param's Prompt"
    ?defValue        car(layerList)
    ?type              "ILList"
    ?storeDefault    "yes"
)

However I keep getting this error when loading the pcell:

*Error* icGetCurrentWindow: invalid cdf parameter type - "ILList"

I've tried ilList and ILList as the parameter type. Why isn't this working?

 BTW, what does CDF stand for? Cadence Design Framework, Cell Database Function, etc?

Edit: Found out what CDF stands for... Component Description Format.

Also, I am trying to change the value of parameters on the instance of a pcell... anyone know how to do that?
I would need to know the object of the parent which instances the pcell.
