    But why add another layer of complexity and a separate file when it is just as
    easy to embed a table in the font with the PUA character properties themselves?

    There is nothing to stop anyone writing and publishing the specs for such a
    custom table which could be added to *any* sfnt format font (TrueType,
    OpenType, AAT, Graphite). Those responsible for writing the rendering systems
    for these fonts could choose whether or not to take any notice of such a table.
