We have a small 2.0reva spec violation by introducing a mojarra behavior.
Mojarra appends always the issuing element in execute (not sure yet if it is also added if none is passed)
The spec clearly states that if @none is passed in execute absolutely nothing is added to the execute list:
Since 2.0 reva is a fairly new spec, I can savely assume this is the expected behavior.
If the keyword @none is present, do not create and send the post data argument javax.faces.partial.execute.
So in reality we have to check for none and do not create anything here
