Bottom line, this 'printer (printed?) perfect is a non starter too.

Printer independent is a must surely.
Perhaps, if it's only a visual comparative. This is getting worse!

Even more flaky at the edges.

So it's viable with 148 pre-conditions. Even then it's manual,
environment dependent etc etc.

I think I'd need a lot more convincing that this was workable as
a model to take forwards.

Not something I've found workable, when interchanging documents
US to UK.
Lines per page buggers that up. "See page X" is no longer meaningful.

I'd bet the ODF standard doesn't. I'm getting the feeling that this
is just a little too far from the standard to be acceptable.
Your knowledge makes that fairly clear Peter.

I doubt anyone would accept screen based comparisons.
This mail has shown that 'layout perfect' is deeply flawed
as a comparator.

Favour please Peter. Could you try and put together
a definition of 'layout perfect', for the definitions page?

Unless that 2% pushes a text flow over onto the next page,
leaving a blank page in the chapter where there wasn't one.

Simpler question. Do you think we could constrain testing
for 'layout perfect' sufficiently for it to be acceptable by, say,
Sun, IBM and the EU?
 If so, what is the list of constraints / pre-conditions?
 What sort of results could we expect?
