    While some FO implementations have built-in fallback font strategies,
    the most correct FO markup requires that you provide a list of fonts
    that the FO processor can step through, e.g.:

    <fo:root font-family="Times, serif, symbol">

    Or some such.

    I think this is an FO problem--the height of the superscript is heigher
    than the normal line height, but I suspect that the FO spec allows
    renderers to recover from this problem in different ways. Both XEP and
    XSL Formatter recover by increasing the line height, rather than
    allowing the raised glyphs to overprint on the line above.

    Cheers,
