I can't say for sure.


SDS's are definitely in the class of "causal systems" in general sense 
of the term.   Wikipedia's definition of "causal system" was a little 
perplexing insomuch as it defined same more in terms of not being 
"acausal" or "anticausal".   I have some intuitions about what the 
latter might mean but would probably continue to muddy the water by 
trying.  It seems relevant that the wikipedia entry for anticausal 
systems refers to them as "hypothetical"?

The point of SDS's are that they are a fairly general, subsuming, 
*formal* description (with computer-based implementations) of causal 
systems.
