I'm sorry if I was unclear. The customization I sent only applies to MathML
content in imagedata, because that element has align and valign attributes.

The equation, inlineequation, and informalequation elements don't have any
alignment attributes. Therefore the customization does not work if you have
MathML as a direct child of any of these elements. 

You can have mediaobject/imageobject/imagedata inside equation. This should
work:

  <equation>
    <mediaobject>
      <imageobject>
	<imagedata align="center">
	  <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML";
id="mymath"> 
        <mml:mrow>
         <mml:mn>Z</mml:mn>
         <mml:mo>=</mml:mo>
         <mml:mn>a</mml:mn>
         <mml:msup><mml:mi>R</mml:mi><mml:mn>b</mml:mn></mml:msup>
       </mml:mrow>
      </mml:math>
     </imagedata>
    </imageobject>
   </mediaobject>
  </equation>
