Matches an li element whose first preceding sibling is not an li element.

Start from the end: self::li selects the context node if it is an li
element, or nothing if it is not.

Within [] this node-set is converted to a boolean, so the predicate
[self::li] is true if the context node is an li element.

preceding-sibling::*[1] selects the first preceding element if there is one.

So preceding-sibling::*[1][self::li] selects the first preceding element if
there is one and it is an li element.

So not(preceding-sibling::*[1][self::li]) returns true if (a) the context
item has no preceding element, or (b) the first preceding sibling element is
not an li element.
