It's the code in CVS.

I don't think there's a performance penalty.  The only sacrifice is that
it's possible a subclass that overrode addContent() to do something
truly "creative" would now also have to override setMixedContent() to
follow the same behavior.  I suspect that would happen anyway with or
without the atomic behavior, so I don't think that's too big a
sacrifice.
