As another example a filter to select all SystemEvents (including derived types) that are contained in the Area1 View or the Area2 View would result in a logic tree as shown in Figure B.2 and a ContentFilter as shown in Table B.2.
Figure B.2 – Filter Logic Tree Example
Table B.2 describes the elements, operators and operands used in the example.
