Prime

What is the correct representation of "X'" in MathML: (1) or (2)?

(1)     <math>
          <msup>
            <mi>X</mi>
            <mo>&#x2032;</mo>
          </msup>
        </math>

(2)     <math>
          <mrow>
            <mi>X</mi>
            <mo>&#x2032;</mo>
          </mrow>
        </math>

The MathML test suite (moAprime16.xml) presupposes (1).

However, the glyph corresponding to &#x2032; in standard Unicode fonts
(for instance, the X11's Misc-Fixed fonts or Microsoft's Arial) is
analogous in height to &#x27;, the ASCII apostrophe. Moreover, only
(2) is rendered as intended by Mozilla.

Yours,
