Gets and sets the property Marker. Use this when paginating results to indicate where
            to begin in your list of origin access identities. The results include identities
            in the list that occur after the marker.    To get the next page of results, set the
            Marker to the value of the NextMarker from the current page's response (which is also
            the ID of the last identity on that page).
