How about: "3.2 Token Elements Token elements in presentation markup are broadly intended to represent the smallest units of mathematical notation which carry meaning. Tokens are roughly analogous to words in text. However, because of the precise, symbolic nature of mathematical notation, the various categories and properties of token elements figure prominently in MathML markup. By contrast, in textual data, individual words rarely need to be marked up or styled specially." My reading of this is that if your dot means differentiation, you should use mover. If x-dot is just some wierd atomic symbol chosen by an eccentric author you should use the unicode.
