BeautifulStoneSoup has no knowledge of any XML vocabulary, so it makes
a set of default assumptions including "tags with the same name can't
be nested." If you have a tag that can be nested inside itself, you
need to subclass BeautifulStoneSoup and add that tag name to
NESTABLE_TAGS. This section of the doc shows how to do that:
