<p class="MsoNormal">> an image of mathematical or engineering equations wouldn’t exactly be the best supporting evidence for encoding them in plain text.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Not only would it not be the best supporting evidence, it wouldn’t be considered supporting evidence _<i>at all</i>_ since math formula layout is not plain text. As Asmus responded,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> what is superscripted is not the individual letter, but the expression. In principle, the superscripted expression is arbitrarily complex and thus the superscript is fully recursive.<o:p></o:p></p>

<p class="MsoNormal">OpenType makeshift? Perhaps you’re not familiar with the MATH table in OpenType, which allows handling all of the typographic nuance in math layout examples such as were shown below.<o:p></o:p></p>
