Hi. > 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? Unfortunately, I think not. This is right on the edge of where content MathML stops.
