KML becomes invalid wrt KML 2.2 schema when saving/exporting already valid KML

[GoogleCodeExporter]

When Google Earth exports or saves KML the order of elements in LookAt tag 
are reverted to listed order in KML 2.1 spec and is no longer valid wrt 
KML 2.2 XML schema whose namespace the KML indicates.

Which products are affected?

Google Earth 5.0

What steps will reproduce the problem?

1. Open any valid KML document with LookAt tag (e.g. original-valid.kml)
2. Either Select "Save As Place.." or "Copy" to export KML locally. See
save-invalid.kml.

Order of tags now as the "listed" order from KML 2.1 spec and fails to 
validate against KML 2.2 XML Schema.

ERROR: SAXParseException org.xml.sax.SAXParseException: cvc-complex-
type.2.4.a: Invalid content was found starting with element 'tilt'. One 
of '{"http://www.opengis.net/kml/2.2":altitudeModeGroup, "http://www.opengi
s.net/kml/2.2":LookAtSimpleExtensionGroup, "http://www.opengis.net/kml/2.2"
:LookAtObjectExtensionGroup}' is expected. 
Line: 18, column: 13
18: <tilt>***65.00146082207077</tilt>

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

Expected Google Earth output to be a valid KML 2.2 document.

What application versions (if any) are you using?

Google Earth 5.0.11733.9347

Which operating systems and browsers are affected?

Microsoft Windows XP but expect all OS versions are affected
