iirc, is in 4.3, but probably works to just take the module and run it
through 4.2 instance.

You will need to do copy operations using different names if you use
AVPs. If you use XAVPs, then you can set a value using index directly.

Not with avp, but with xavp -- you can just add x in front of those avps
