// We have a bit of a problem here. MathML wants to know whether the
// character represents an "identifier" or an "operator", and we have
// no general way of telling. So we shall guess: If it's alpha or 
// mathalpha, then we'll treat it as an identifier, otherwise as an 
// operator.
// Worst case: We get bad spacing, or bad italics.
