Convert a Google Earth KmlPolygon into KML string

Question

If I have a KmlPolygon object, how might I convert this to a KML string? This functionality would allow you to save whatever has been modelled and use it as a layer in Google Earth desktop for instance, or even load it back into the web plugin.

EDIT

This would do the opposite of fetchKml.

Found it. You can use the getKml() function of KmlFeature to return the KML string. You can also add multiple KmlPolygon objects by constructing a KmlDocument using the dom.buildDocument() of the utility library, and then using getKml() on that.
