Point 3 should read: "GFDL document +

Those other two clauses are significant. Aggregates, as I understand
them,
are resticted to combinations of documents that
are functionally
independent
and connected merely by proximity in a
distribution medium, etc.
That may be, although I have doubts that "volume" implies
"functionally independent" here. However, it's a word that's
ill-defined here and so I have no evidence to cite one way or the
other.
4) GFDL document augmented by non-GFDL text or

(derivative).
They way I understand it is basically: If you can remove either work
without
materially affecting the reader's
understanding of the remaining work
then
it can be an aggregate. If, on the other hand,
the understanding and
appreciation of one work depends on the presense of the other, then the
collective work fails the "separate and independent" test must be
treated as
a derivative and not as an aggregate.
No, this cannot possibly be true. For example, let's say you have a
document, A, that is GFDL. I have a picture, B, over which I maintain
a non-free copyright. You cannot make document C = A + B, and say that
C is GFDL, because that violates my copyright on B. You either need to
invoke fair use, or else C must be an aggregate that does not affect
the licenses on either A or B. Comparing sizes, just because A > B
doesn't mean that the copyright for A is more important then the
copyright on B, or that A's copyright license "wins" because it's more
substantial.
Including my image B in a large composite work C that is mostly
comprised of GFDL text A does not make C a GFDL document. From the
GFDL itself: "A 'Modified Version' of the Document means any work
containing the Document or a portion of it". If C = A + B, and C is
GFDL, then B is a portion of C, and therefore B is GFDL too. However,
this is impossible, because I hold exclusive non-free copyright over B
and never released it under the GFDL. C, therefore, cannot be a GFDL
document because all it's parts are not GFDL documents (unless, again,
we invoke fair use).
Perhaps I was unclear above. My implication is that combining GFDL works +
non-GFDL works in a composite inter-dependent document requires being able
to also license the non-GFDL works under the GFDL. Anything less is a
violation of the GFDL license on the original work.
You seem to follow this implication exactly, except that you reject it. My
understanding of the GFDL is that it would be a violation of the license to
create composite work C while including unfree image B. Without obtaining a
free license on image B (or perhaps invoking fair use), the GFDL (as I
understand it) prevents you from tainting free work A by combining it with
unfree image B. In other words, creating the composite work C would be a
violation of the license you were granted to use A. So in this case, the
license restrictions on A do "win" since they limit the ways that A may be
combined with other works.
Of course, in general, this may mean you are forbidden from creating C since
it may be impossible to obtain that free license on B.
Is that really so strange? The GFDL's commitment to free content includes
wanting to ensure that free documents aren't "improved" via the
incorporation of unfree information that might in turn make all future
versions unfree. All versions of GFDL documents must be built out of free
content.
