* Use this method instead of a direct call to {@link Xpp3Dom#mergeXpp3Dom(Xpp3Dom, Xpp3Dom)}.
* Profiles are dominant, thus they are merge targets, but they may be merged in several times
* (e.g. if they are inherited). So with the second merge, you don't get the profile's original
* DOM, but an already merged one.
