It is my understanding of US copyright law that each co-owner of
a work has an independent right to use or non-exclusively license 
the use of a work.

There is also no need for a specific statutory provision concerning the
rights and duties of the coowners of a work; court-made law on this point is
left undisturbed. Under the bill, as under the present law, coowners of a
copyright would be treated generally as tenants in common, with each coowner
having an independent right to use or license the use of a work, subject to
a duty of accounting to the other coowners for any profits.

In Germany all copyright holders need to consent to a license granted 
by any one copyright holder.

I mean they are not part of the license. True, they are on the
same document, but they are not a license term.

The GNU GPL (v3) is the text from "GNU GENERAL PUBLIC LICENSE" up to
and including "END OF TERMS AND CONDITIONS" on the page
[the same applies to GPLv2]

Everything above and below (and to the side) of that is not
part of the license document. I don't see how a text that is
below a marker "END OF TERMS AND CONDITIONS" can be considered
part of a license.
