l) Preserve all the Invariant Sections of the Document, unaltered in their text
and in their titles. Section numbers or the equivalent are not considered
part of the section titles.
m) Delete any section entitled "Endorsements". Such a section may not be
included in the Modified Version.
n) Do not retitle any existing section as "Endorsements" or to conflict in title
with any Invariant Section. If the Modified Version includes new front-
matter sections or appendices that qualify as Secondary Sections and
contain no material copied from the Document, you may at your option
designate some or all of these sections as invariant. To do this, add their
titles to the list of Invariant Sections in the Modified Version’s license
notice. These titles must be distinct from any other section titles. You may
add a section entitled "Endorsements", provided it contains nothing but
endorsements of your Modified Version by various parties_for example,
statements of peer review or that the text has been approved by an
organization as the authoritative definition of a standard. You may add a
passage of up to five words as a Front-Cover Text, and a passage of up to
25 words as a Back-Cover Text, to the end of the list of Cover Texts in the
Modified Version. Only one passage of Front-Cover Text and one of
Back-Cover Text may be added by (or through arrangements made by) any
one entity. If the Document already includes a cover text for the same
cover, previously added by you or by arrangement made by the same entity
you are acting on behalf of, you may not add another; but you may replace
the old one, on explicit permission from the previous publisher that added
the old one.
The author(s) and publisher(s) of the Document do not by this License give
permission to use their names for publicity for or to assert or imply
endorsement of any Modified Version.
4. Combining Documents
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. 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
