It is added according to the following rules.
Priority must have three, four, or five characters. It starts with an angle bracket "<", followed by a number, followed by
an angle bracket ">". Example: <14>
The Priority value is calculated from the Facility code (Facility) and the Severity code (Severity). The Priority value
consists of one, two, or three decimal integers.
The Priority value is calculated by first multiplying the Facility code by 8 and then adding the numerical value of the
Severity code.
