From your comments it appears that you are trying to use a test assertion
for all levels. I'm clear that's not right.

At some level a Turing complete language will be required.
It's unreasonable to lump all this into a declarative assertion statement(s).

If it's informative it's not tested? Tests only test firm requirements.
Further, only requirements which are verifiable.



At some point a clear scoping document/paragraph/section will be
needed to draw a line above which TAG is not interested.

From this thread I'd suggest that the line is close, but below, the
application layer?
