Thankyou for your explanation.

Indeed not; this was not a requirement for the document.  Instead I was 
aiming to identify all the root logical problems from which specific 
practical problems arise (and then, in the two supplementary proposal 
documents referenced from within the main document, to suggest 
rewordings which resolve all the root problems identified).

In response for your request for test cases, I have created the following:

http://dev.moonhenge.net/css21/spec/z-index/testcases/stacking-level-for-floats.html
(A problem concerning the stacking level for floats)

http://dev.moonhenge.net/css21/spec/z-index/testcases/stacking-level-for-floats-2.html
(A second problem concerning the stacking level for floats)

http://dev.moonhenge.net/css21/spec/z-index/testcases/stack-level-of-non-positioned-elements.html
(A problem concerning the stack level of non-positioned elements)

I hope that these illustrate the most pressing practical problems 
successfully enough to enable the WG to assess them relatively quickly, 
even if it chooses not to rectify them (or, of course, detects a flaw in 
my reasoning).  If I still have not correctly understood your 
requirements, please explain further and I will attempt to meet them again.

Cheers,

Anton Prowse
