Cool, I tend to be in agreement too.
My one issue (not real big) with this is that for the foo element:
The getMixedContent() List of content will include solely a "bar"
element, no empty string elements. Somehow that doesn't feel right.
But neither does returning null. :-)

I don't see that as an issue. We wouldn't be adding a null to any list
in response to that call. We'd just be doing content.clear() on the
list, because setText() replaces all content. (If you want to add a
string you say addContent("whatever").)
