"""Tree builder compatibility suite.
If you create a tree builder class, also create a test suite that
subclasses this one. This test suite will parse various bits of
well-formed HTML with your tree builder. Not every tree builder will
handle bad HTML in the same way, but every builder should be able to
handle _good_ HTML in the same way.
