At this point, I'm not sure what kind of low-level API we want to make
available to the library user (by low-level, I mean letting people directly
poke at the xmlNode wrapped in a GVirConfigObject instance). That's why I
chose not to export them for now, and to make them public if/once they are
needed.
If you think they should be exported, I'll make the change.
