Is there an accepted notation for marking up directional (ie. vector) derivatives (http://mathworld.wolfram.com/DirectionalDerivative.html) in content MathML? My first inclination was to use the <gradient> tag, but that's not quite correct since it's really the dot product of the gradient and the unit direction vector. Is the <diff/> tag appropriate here? How would I specify the directional vector? A <bvar> perhaps?
