One could create a zero_vector OpenMath symbol (or equivalent), taking one
argument (sibling in the XML tree), for the length. Then refer to this
with a MathML semantics or csymbol element.


P.S. info on OpenMath may be obtained at
P.P.S this zero vector symbol should probably go in the content dictionary
linalg6, this may be contributed from the OpenMath contribution page:
