question about namespace:

Is it true that child elements don't automatically inherit namespace
of parent element?
In this example the tr_string element is not automatically in 'trans'
namespace?

<trans:tr page_id="global">
        <tr_string str="recent_albums">
            <en>
                Recent Albums
            </en>
            <ru>
                nOWYE ALXBOMY
            </ru>
        </tr_string>


    </trans:tr>
