You don't need to change the XML file at all. The XML merging happens at
runtime in memory with help of the KXMLGUIClient and KXMLGUIFactory classes.

This is exactly what KPart Plugins do for example. See all those Konqueror
plugins in kdeaddons? They all provide a small XMLGUI (*.rc) file with the
location of where their actions are supposed to be merged into the GUI.
