You could theoretically replace every element of a ray-tracer with
interpreted (by interpreted I/we mean software-interpreted) code.  The
question is, "would you want to?"  For example, the calculation for the
example that you gave is computed MANY times as a scene is traced.  You'd
only want to use an interpreted version if you needed to.  On the other
hand, it would be nice to provide the option to use interpreted code if the
desired feature was not implemented in the core functionality.  But you
could do this fairly easily without using XML.
