Now,  in the next example  you declare the mml name space
and the you use it  only for
<mml:math>and </mml:math>
--- all the other nodes that are not in the mml namespace are skipped.
But with
<msubsup xmlns="http://www.w3.org/1998/Math/MathML">
you still declare the MathML namespace, so they are ok
and then  with
<mrow>
        <mover accent="true">
                <mrow>
                        <msub>
                                <mi>U</mi>
                                <mi>A</mi>
                        </msub>
                </mrow>
                <mo>&OverBar;</mo>
        </mover>
</mrow>
you are again *outside* the MathML namespace so they are your private markup
and context doesn't render as MathML --- after all they are your private
markup.
