RTYP missing in policy for non .VAL
Brought to you by:

It seems that the 'RTYP' key is sometimes missing for the information passed to the policy callback. In this case the PV being archived was the .INDX field of a subArray record.
I would guess that the appliance is attempting to read "pvname.INDX.RTYP". A better strategy would be to get DBR_CLASS_NAME which works for all fields, including non-VAL.
