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.
