1. Use CSS3 rules such as li:n-th-child(even) and/or
li:n-th-child(odd) [1]. Unfortunately, these don't work in IE [2].

2. Add the markup expression {(math)} [3], and then use the
conditional (:if equal 1 {(math {$$PageCount} % 2)}:)

3. Add a custom conditional:
    $Conditions['odd'] = 'intval($condparm) % 2';
and then use it: (:if odd {$$PageCount}:)

Is there a use case where the same result can't be achieved with
already existing markup?
