Then refer to this with a MathML semantics or csymbol element. Bill P.S. info on OpenMath may be obtained at http://openmath.org P.P.S this zero vector symbol should probably go in the content dictionary linalg6, this may be contributed from the OpenMath contribution page: http://monet.nag.co.uk/cocoon/openmath/cdfiles/collections/contributed.html
