Tests of key signature cancellation: in measure 2 it is positioned at the default location (which usually means that the cancellation comes immediately after the bar line), in measure 3 it uses the attribute ‘location="right"’ (i.e., the cancellation comes after the new key signature), in measure 4 it uses ‘location="before-barline"’, and in measure 5 it uses the attribute ‘location="left"’ (the cancellation comes before the new key signature). The <cancel> element's value (4) in the last measure intentionally doesn't correspond to the value of the previous <fifths> value (2) for testing purposes.
