You are mixing things here that don't belong together and that's also 
the source of your misunderstanding.  Try first to understand the terms 
you are using here and you will see that it does not make sense.

To sum it up:

- it does not make any sense to add a displacement mapping feature to 
any higher level shape in POV-Ray that is internally rendered as a mesh.
- it is not possible to add a displacement feature to any shape POV-Ray 
renders analytically.

==> the only shape that could profit from a displacement mapping feature 
is the mesh but apart from render time subdivision with displacement 
this is already possible to implement in SDL (or external programs).
