Agent Builder interprets the types of property variables, as follows:
An integer is substituted with its actual value (300, for example).
A Boolean value is substituted with the string TRUE or FALSE.
A string is substituted with the actual string (phys-node-1, for example).
A list of strings is substituted with all members in the list, each string separated by a comma (phys-node-1,phys-node-2,phys-node-3, for example).
A list of integers is substituted with all members in the list, each integer separated by a comma (1,2,3, for example).
An enumerated type is substituted with its value, in string form.
