I think it's educational. That's important for this XEP - since there

narrow. So anyone can decide to do their own thing (all too common with 
crypto code). We can't stop that, but we can at least help them avoid 
the obvious mistakes.

I'm also interested in 4.1 (why the Originating Server needs to be 
included). :-)
