OpenSearch Geo Extensions KML Response violates KML 2.2 spec

[JasonM1]

The KML response example in the OpenSearch Geo extensions DRAFT
violates the OGC KML 2.2 specification.

<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:atom="http://
www.w3.org/2005/Atom"
xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/"
xmlns:geo="http://a9.com/-/opensearch/extensions/geo/1.0/">

<!-- non-KML namespace elements not allowed in kml element -->
<opensearch:totalResults>4230000</opensearch:totalResults>
<opensearch:startIndex>21</opensearch:startIndex>
<opensearch:itemsPerPage>10</opensearch:itemsPerPage>
<opensearch:Query role="request" searchTerms="New York History"
startPage="3" geo:box="-74.0667,40.69418,-73.9116,40.7722"/>
....

Example from http://www.opensearch.org/Specifications/OpenSearch/Extensions/Geo/1.0/Draft_2#KML_Response

An alternative representation that conforms to the KML 2.2 spec could
use an ExtendedData element on the outer-most Document with the
opensearch elements as arbitrary XML with an explicit namespace.
