[tag] expression

Mathematical expression of a function. For non-scalar values, an expression should be given for each component.

Currently x,y,z, and t are supported variables, and curves from the <curves> section can be called using their names. A curve is a single argument function and can be used in an expression like curveA(sin(t)).
