    And I would second this third approach. ;-)

    It would be very useful to have a written explanation of
    the behavior of visarga and ardhavisarga to help guide
    rendering implementations. Note that there are many
    many extensions for Vedic added in Unicode 5.2, and
    the addition of the ardhavisarga is not the only character
    which implementations will need new information about
    in order to get best display behavior -- but it is
    a good place to start.

    Shriramana Sharma's discussion which started this thread,
    shorn of assumptions about what "should" or "should not"
    be a combining mark, and instead focussing on the actual
    display behavior required, could seed such a written
    explanation. It could start existence as a FAQ (or
    set of FAQ entries) or a UTN -- and if it proves helpful,
    then be reworked to incorporate it as appropriate in
    the relevant sections of the standard, if the UTC approves
    heading in that direction.
