You may combine the Document with other documents released under this
License, under the terms defined in section
4 above for modified versions, provided that you include in the
combination all of the Invariant Sections of all of the original
documents, unmodified, and list them all as Invariant Sections of your
combined work in its license notice, and that you preserve all their
Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single copy. If
there are multiple Invariant Sections with the same name but different
contents, make the title of each such section unique by adding at the end of
it, in parentheses, the name of the original author or publisher of that
section if known, or else a unique number. Make the same adjustment to the
section titles in the list of Invariant Sections in the license notice of the
combined work.
In the combination, you must combine any sections Entitled "History" in
the various original documents, forming one section Entitled "History";
likewise combine any sections Entitled "Acknowledgements", and any sections
Entitled "Dedications". You must delete all sections Entitled "Endorsements".
