A data (MIME) type and a priority value for that data type.

The priority is used to resolve the current preferred handler of a data type, in the absence of any user preferences. An AIF file can associate an application with a data (MIME) type that is not native to Symbian OS. A priority value can be specified that allows the device to choose the highest priority application that can handle that data type.
