I have just added these as presentation styles to the inline emphasis tag:

        There has been a lot of interest lately in
        mc<emph tag="super">2</emph>.
i.e                                                  2
        There has been a lot of interest lately in mc .

        (HP-speak for measurement, computation and communication)

The suggestions for rendering emphasis are:

    a)  allow users to tailor the display via user prefernces
        e.g. italic, bold, underline, highlight, super/subscript

    b)  default to italic or highlighted text for unrecognised types

These changes will make their way to the CERN copy soonish.

p.s. Does anyone mind if I change the generic emphasis tag from EMPH to EM?
