But they implement the same interface (DOM in this case) and the XML for
Java standard says that the DOM interface classes have to be in the package
org.w3c.dom - so there is no way around this.

Yes it is if they implement the same specification. Other examples might
be SAX (org.w3c.sax) and EJB (javax.ejb): Each EJB container will
provide all required classes in the javax.ejb package. The classes for
interfaces might be identical for all containers but at least the exception
classes will differ - so it is very difficult to put the common classes in
another JAR/package ans share them between all implementations.
