This statement about XML is not helpful without reference to a
particular document type.

For example, gellmu article does provide elements called "math" and
"displaymath", which when formatted to LaTeX switch on the
corresponding math mode.

As LaTeX is evolving it will be possible for gellmu's "alpha" (an
empty element marked up in Gellmu source as \alpha) to be formatted in
LaTeX as (math) \alpha when recursively inside a math element and not
inside either of gellmu's "mbox" or "text", while outside of math
"alpha" could easily be morphed to a suitable unicode point.

That's roughly the number of points in a single plane of unicode.  The
current design provides 16 planes, but I believe that less than half
are defined.  Not all of these points correspond to simple glyphs.
For example, some points are combining characters.
