I second this suggestion.

We currently mark up mixed fractions like this:
       <mml:mrow>
         <mml:mn>3</mml:mn>
         <mml:mfrac>
           <mml:mn>1</mml:mn>
           <mml:mn>4</mml:mn>
         </mml:mfrac>
       </mml:mrow>

Adding some presentation support (such as &InvisiblePlus;) would clarify 
the markup and possibly allow removal of the mrow.
