Adding a suffix of "-no-invarients"  to "GFDL-1.1-or-later"  is still under
discussion on the SPDX license list,  and the syntax should probably
be GFDL-1.1-no-invariants-or later.

I've added a comment to the SPDX pull request to this effect,
so best to hold off on applying this until it gets through the
review process on the SPDX list.

see above - I believe it should be GFDL-1.2-no-invariants-only,  but
we need to sort this on the SPDX legal list before it gets applied.

> +2. VERBATIM COPYING
> +
> +You may copy and distribute the Document in any medium, either
> +commercially or noncommercially, provided that this License, the
> +copyright notices, and the license notice saying this License applies
> +to the Document are reproduced in all copies, and that you add no other
> +conditions whatsoever to those of this License.  You may not use
> +technical measures to obstruct or control the reading or further
> +copying of the copies you make or distribute.  However, you may accept
> +compensation in exchange for copies.  If you distribute a large enough
> +number of copies you must also follow the conditions in section 3.
> +
> +You may also lend copies, under the same conditions stated above, and
> +you may publicly display copies.
> +
> +
> +3. COPYING IN QUANTITY
> +
> +If you publish printed copies (or copies in media that commonly have
> +printed covers) of the Document, numbering more than 100, and the
> +Document's license notice requires Cover Texts, you must enclose the
> +copies in covers that carry, clearly and legibly, all these Cover
> +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
> +the back cover.  Both covers must also clearly and legibly identify
> +you as the publisher of these copies.  The front cover must present
> +the full title with all words of the title equally prominent and
> +visible.  You may add other material on the covers in addition.
> +Copying with changes limited to the covers, as long as they preserve
> +the title of the Document and satisfy these conditions, can be treated
> +as verbatim copying in other respects.
> +
> +If the required texts for either cover are too voluminous to fit
> +legibly, you should put the first ones listed (as many as fit
> +reasonably) on the actual cover, and continue the rest onto adjacent
> +pages.
> +
> +If you publish or distribute Opaque copies of the Document numbering
> +more than 100, you must either include a machine-readable Transparent
> +copy along with each Opaque copy, or state in or with each Opaque copy
> +a computer-network location from which the general network-using
> +public has access to download using public-standard network protocols
> +a complete Transparent copy of the Document, free of added material.
> +If you use the latter option, you must take reasonably prudent steps,
> +when you begin distribution of Opaque copies in quantity, to ensure
> +that this Transparent copy will remain thus accessible at the stated
> +location until at least one year after the last time you distribute an
> +Opaque copy (directly or through your agents or retailers) of that
> +edition to the public.
> +
> +It is requested, but not required, that you contact the authors of the
> +Document well before redistributing any large number of copies, to give
> +them a chance to provide you with an updated version of the Document.
> +
> +
> +4. MODIFICATIONS
> +
> +You may copy and distribute a Modified Version of the Document under
> +the conditions of sections 2 and 3 above, provided that you release
> +the Modified Version under precisely this License, with the Modified
> +Version filling the role of the Document, thus licensing distribution
> +and modification of the Modified Version to whoever possesses a copy
> +of it.  In addition, you must do these things in the Modified Version:
> +
> +A. Use in the Title Page (and on the covers, if any) a title distinct
> +   from that of the Document, and from those of previous versions
> +   (which should, if there were any, be listed in the History section
> +   of the Document).  You may use the same title as a previous version
> +   if the original publisher of that version gives permission.
> +B. List on the Title Page, as authors, one or more persons or entities
> +   responsible for authorship of the modifications in the Modified
> +   Version, together with at least five of the principal authors of the
> +   Document (all of its principal authors, if it has fewer than five),
> +   unless they release you from this requirement.
> +C. State on the Title page the name of the publisher of the
> +   Modified Version, as the publisher.
> +D. Preserve all the copyright notices of the Document.
> +E. Add an appropriate copyright notice for your modifications
> +   adjacent to the other copyright notices.
> +F. Include, immediately after the copyright notices, a license notice
> +   giving the public permission to use the Modified Version under the
> +   terms of this License, in the form shown in the Addendum below.
> +G. Preserve in that license notice the full lists of Invariant Sections
> +   and required Cover Texts given in the Document's license notice.
> +H. Include an unaltered copy of this License.
> +I. Preserve the section Entitled "History", Preserve its Title, and add
> +   to it an item stating at least the title, year, new authors, and
> +   publisher of the Modified Version as given on the Title Page.  If
> +   there is no section Entitled "History" in the Document, create one
> +   stating the title, year, authors, and publisher of the Document as
> +   given on 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 Document for previous versions
> +   it was based on.  These may be placed in the "History" section.
> +   You may omit a network location for a work that was published at
> +   least four years before the Document itself, or if the original
> +   publisher of the version it refers to gives permission.
> +K. For any section Entitled "Acknowledgements" or "Dedications",
> +   Preserve the Title of the section, and preserve in the section all
> +   the substance and tone of each of the contributor acknowledgements
> +   and/or dedications given therein.
> +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 to be Entitled "Endorsements"
> +   or to conflict in title with any Invariant Section.
> +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 or to assert or
> +imply endorsement of any Modified Version.
> +
> +
> +5. 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, 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".
> +
> +
> +6. COLLECTIONS OF DOCUMENTS
> +
> +You may make a collection consisting of the Document and other documents
> +released under this License, and replace the individual copies of this
> +License in the various documents with a single copy that is included in
> +the collection, provided that you follow the rules of this License for
> +verbatim copying of each of the documents in all other respects.
> +
> +You may extract a single document from such a collection, and distribute
> +it individually under this License, provided you insert a copy of this
> +License into the extracted document, and follow this License in all
> +other respects regarding verbatim copying of that document.
> +
> +
> +7. AGGREGATION WITH INDEPENDENT WORKS
> +
> +A compilation of the Document or its derivatives with other separate
> +and independent documents or works, in or on a volume of a storage or
> +distribution medium, is called an "aggregate" if the copyright
> +resulting from the compilation is not used to limit the legal rights
> +of the compilation's users beyond what the individual works permit.
> +When the Document is included in an aggregate, this License does not
> +apply to the other works in the aggregate which are not themselves
> +derivative works of the Document.
> +
> +If the Cover Text requirement of section 3 is applicable to these
> +copies of the Document, then if the Document is less than one half of
> +the entire aggregate, the Document's Cover Texts may be placed on
> +covers that bracket the Document within the aggregate, or the
> +electronic equivalent of covers if the Document is in electronic form.
> +Otherwise they must appear on printed covers that bracket the whole
> +aggregate.
> +
> +
> +8. TRANSLATION
> +
> +Translation is considered a kind of modification, so you may
> +distribute translations of the Document under the terms of section 4.
> +Replacing Invariant Sections with translations requires special
> +permission from their copyright holders, but you may include
> +translations of some or all Invariant Sections in addition to the
> +original versions of these Invariant Sections.  You may include a
> +translation of this License, and all the license notices in the
> +Document, and any Warranty Disclaimers, provided that you also include
> +the original English version of this License and the original versions
> +of those notices and disclaimers.  In case of a disagreement between
> +the translation and the original version of this License or a notice
> +or disclaimer, the original version will prevail.
> +
> +If a section in the Document is Entitled "Acknowledgements",
> +"Dedications", or "History", the requirement (section 4) to Preserve
> +its Title (section 1) will typically require changing the actual
> +title.
> +
> +
> +9. TERMINATION
> +
> +You may not copy, modify, sublicense, or distribute the Document except
> +as expressly provided for under this License.  Any other attempt to
> +copy, modify, sublicense or distribute the Document is void, and will
> +automatically terminate your rights under this License.  However,
> +parties who have received copies, or rights, from you under this
> +License will not have their licenses terminated so long as such
> +parties remain in full compliance.
> +
> +
> +10. FUTURE REVISIONS OF THIS LICENSE
> +
> +The Free Software Foundation may publish new, revised versions
> +of the GNU Free Documentation License from time to time.  Such new
> +versions will be similar in spirit to the present version, but may
> +differ in detail to address new problems or concerns.  See
> +https://www.gnu.org/licenses/.
> +
> +Each version of the License is given a distinguishing version number.
> +If the Document specifies that a particular numbered version of this
> +License "or any later version" applies to it, you have the option of
> +following the terms and conditions either of that specified version or
> +of any later version that has been published (not as a draft) by the
> +Free Software Foundation.  If the Document does not specify a version
> +number of this License, you may choose any version ever published (not
> +as a draft) by the Free Software Foundation.
> +
> +
> +ADDENDUM: How to use this License for your documents
> +
> +To use this License in a document you have written, include a copy of
> +the License in the document and put the following copyright and
> +license notices just after the title page:
> +
> +    Copyright (c)  YEAR  YOUR NAME.
> +    Permission is granted to copy, distribute and/or modify this document
> +    under the terms of the GNU Free Documentation License, Version 1.2
> +    or any later version published by the Free Software Foundation;
> +    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
> +    A copy of the license is included in the section entitled "GNU
> +    Free Documentation License".
> +
> +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
> +replace the "with...Texts." line with this:
> +
> +    with the Invariant Sections being LIST THEIR TITLES, with the
> +    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
> +
> +If you have Invariant Sections without Cover Texts, or some other
> +combination of the three, merge those two alternatives to suit the
> +situation.
> +
> +If your document contains nontrivial examples of program code, we
> +recommend releasing these examples in parallel under your choice of
> +free software license, such as the GNU General Public License,
> +to permit their use in free software.
