its Title Page, then add an item describing the Modified Version as stated in the
previous sentence.
J. Preserve the network location, if any, given in the Document for public access to a
Transparent copy of the Document, and likewise the network locations given in the

the section, and preserve in the section all the substance and tone of each of the
contributor acknowledgements and/or dedications given therein.

the Modified Version.
N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title

O. Preserve any Warranty Disclaimers.
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 orto assert or imply endorsement of any Modified Version.
