That's not my understanding of form-content merger, though it is close.
In U.S. law, if there is *only one sensible way* of expressing something,
then that expression is inherently uncopyrightable. If I prepare a list
of the towns in New York State in alphabetical order, it does not matter
how many others have done the same, or even if I copied from their work.
The list is simply too trivial to meet even the relaxed standard of
"originality" which copyright law applies.

I agree.

Well, I will squelch the thread using a counterexample. IBTWSH
is by intention an expression of the same schema as (part of) HTML 4.0.
However, it is an independently derived work, which I wrote based on
my *understanding* of HTML 4.0. If I had simply copied the W3C
version and deleted everything which I didn't wish to include in my
subset, it would be a derivative work, but I didn't do that.
I did, of course, verify (by hand) IBTWSH against HTML 4.0 to
make sure it was a true subset, but that does not interfere with
its copyright status, any more than verifying one dictionary against
another does so, as long as portions of the verifying dictionary
do not find their way into the verified dictionary.
