In both the L2v4 and L3v1 specs (and previous specs, too), the XML examples in the 'SpeciesReference' section contains closing tags that are called 'listProducts' instead of 'listOfProducts'. Whoops!
I'm going ahead and marking this 'pending' and 'Accepted-formatting-and-typos', because it's such an obvious typo.
(And, added to the list of errata for both specs.)
Fixed in SVN for both L2v5 and L3v2, and will be part of the forthcoming release of those specifications.
