What is the difference between stating language1 and language2 have *mapping 1:1* and stating that a *cardinality 1:1* exists between language1 and language2?
This seems to be a communication problem.

What puzzles me here is that we are using a concept of cardinality/ mapping for languages / models when I believe such concept applies only to something that can be quantified . I hope this clarifies my intent. I believe this is vague.
