I'd like to know the exact same thing.  Been doing taxes for 40 years.  Before Turbo Tax was in existence.  I waited and refiled on Feb 23.  Still received a rejected return.  Now it is saying March 8.  No explanation regarding XML or binary document.  As you stated.  What exactly does that mean?  I called Turbo Tax and the agent was literally reading the same blog I was reading.  Zero help or explanation by their professionals.  I am beyond frustrated.
