The problem has nothing to do with improving display. As I said, that
will be via an image such as a GIF or PNG. The microformat is solely for
the purpose of associating a MathML or TeX representation with the
image. As with other microformats, normal HTML content is what the user
sees while software sees structured, useful data.
