+There are a number of problems with the XML on the wire. Even if we

+The <Notes> elements here are supposed to be associated with a set of
+<Game> elements, but since the pair
+(<Notes>...</Notes><Game>...</Game>) can appear zero or more times,
+this leads to ambiguity in parsing. We therefore ignore the notes
+entirely (although a hack is employed to facilitate parsing).

+There appear to be two types of weather documents; the first has
+<listing> contained within <forecast> and the second has <forecast>
+contained within <listing>. While it would be possible to parse both,
+it would greatly complicate things. The first form is more common, so
+that's all we support for now.
