Well, as you ask, me! I transform some solid object in mesh, then
deform them in pov. (personnal edition, of course...)

I'm afraid of a chicken-egg issue in this sterile discussion about SDL.
A full clean-up of the data model would be needed first (far away
from the SDL, at the lowest memory level). Once the future data
model is stable (and beautiful ?), we could look at any rendering
algorithm to see if it fit the actual data or require an extension
(or a bigger evolution). That's something that cannot be done "on
the wind", you need a practical algorithm. Documenting the
data-model could save the trouble for the future generation.
Then, with a reliable data-model, you can have any loony designs its
own SDL to fill that data (or explore it, too). You can even
anticipate a serialisation of the actual data, for easier
saving/loading (including distributed rendering). And again, the
serialisation can be done in whatever loony's designed syntax (XML,
ASN.1 (BER or PER or whatever), bytecode, ...) they want it.

The purpose of parsing is to generate the data for the rendering
engine, everything else are just commodities for the users.
