Slurs on chorded notes. The upper slur connects the first and third chord; for both the start and end, the <slur> element is attached not to the first note of the chord but to the second one (tagged with <chord>). The lower slur connects the chord on the second beat and the note on fourth beat and is attached in the normal way.
