I have somewhat updated my viewpoint.
I have rewritten sections 2 and 3 in
http://altair.fiit.stuba.sk/mediawiki/upload/2/2d/Sofsem2010.pdf
Now I draw some analogies of our two properties with which we are concerned:
- defensive consistency
- defensive correctness
with other safety or liveness properties. The new text makes more sense
to. I must yet update the rest of the paper.
