[Name] ATTRIBUTE_TYPE

[Description] Prompts user to enter or select an attribute type. By default, 
              if the parameter is not optional, the current attribute type
              will be shown. A modal pop up allows user to pick an attribute type.  
              Users can also edit the attribute type directly by clicking the 
              text field and typing in it. Return string conforms to FME's attribute
              type specification of <type-name>[(width[,precision])]

              The type is only supported in Json.
