triviainfo.xml is not "well formed"

The triviainfo.xml file has more than one element in its root. According to the XML 1.0 standard this is known as a not well formed doc, apparently.

Anyway, ant complaints.

I wrapped everything under <?xml in a <trivia> tag, since I don’t think this file is even being used anywhere.
