Memory Leak, SWIG does not produce destructor for some elements

[GoogleCodeExporter]

What steps will reproduce the problem?

import kmldom
val = '<Polygon></Polygon>'
element = kmldom.ParseKml(val)
TypeDict =
{kmldom.Type_Metadata:kmldom.AsMetadata(element),kmldom.Type_XalAddressDetails:k
mldom.AsXalAddressDetails(element),kmldom.Type_XalAdministrativeArea:kmldom.AsXa
lAdministrativeArea(element),kmldom.Type_XalCountry:kmldom.AsXalCountry(element)
,kmldom.Type_XalLocality:kmldom.AsXalLocality(element),kmldom.Type_XalPostalCode
:kmldom.AsXalPostalCode(element),kmldom.Type_XalSubAdministrativeArea:kmldom.AsX
alSubAdministrativeArea(element),kmldom.Type_XalThoroughfare:kmldom.AsXalThoroug
hfare(element),
}
TypeDict[kmldom.Element.Type(element)]
TypeDict =
{kmldom.Type_Metadata:kmldom.AsMetadata(element),kmldom.Type_XalAddressDetails:k
mldom.AsXalAddressDetails(element),kmldom.Type_XalAdministrativeArea:kmldom.AsXa
lAdministrativeArea(element),kmldom.Type_XalCountry:kmldom.AsXalCountry(element)
,kmldom.Type_XalLocality:kmldom.AsXalLocality(element),kmldom.Type_XalPostalCode
:kmldom.AsXalPostalCode(element),kmldom.Type_XalSubAdministrativeArea:kmldom.AsX
alSubAdministrativeArea(element),kmldom.Type_XalThoroughfare:kmldom.AsXalThoroug
hfare(element),
}

What is the expected output? What do you see instead?

This is not a high priority because these elements have all been phased
out, but I ran into this error trying to make a dictionary of all of the
elements. Thought it would be good to pass this along. Thanks!
