Status of ODF 1.3 implementation in LibreOffice 7.0

On the master branch (and also libreoffice-7-0), the default ODF version 
is the newly added ODF 1.3 Extended; ODF 1.3 is also a newly available 
option.

For developers who want to add new ODF extensions, we would like to 
point out the behavioral change in commit
f1dbaac9e4b68941d845a5f0ab7b204e12de14de "xmloff: ODF export: rework 
version checks in SvXMLExportPropertyMapper"
(see commit message) that should simplify things a little bit.

* ODF Toolkit:

The ODF Validator can now validate ODF 1.3 documents, both in the 0.9 
and 1.0 branches; the only missing feature is recognition of the new ODF 
Global Document Template media type, which requires ODFDOM to support 
ODF 1.3 first, so for this bit there are only pull requests that can't 
be merged yet.

* Wiki:

Release notes are updated:

https://wiki.documentfoundation.org/ReleaseNotes/7.0#ODF_1.3

The page with instructions for adding new ODF extensions was adapted to 
changes:

https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes

There is the page that (supposedly) lists all of the ODF extensions 
implemented by LO:

https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_Extensions

We found that it didn't list 3 of the extensions that were implemented 
in ODF 1.3, which isn't too bad, but then we also found 39 more unlisted 
extensions that will have to be added to ODF 1.4 or later, which is 
really quite a surprising number. Not sure what could be done to 
incentivise keeping the Wiki up to date with new extensions...

It would be particularly helpful to expedite the extensions that are 
currently written erroneously into standard namespaces, so that by the 
time the next ODF version is finished, we can continue writing to the 
standard namespaces instead of switching to writing exclusively to 
extension namespaces; see the following commits:

> 686d171303c3e9bbddf885ddfcfa65c5cb019733 sc: ODF export: style:hyperlink extensi on element, step 1
> 7f41eb8768160f79297712f3ac61a25a72dcd5a0 xmloff: ODF export: fix style:hidden nonsense, step 1

* Backports for LTS branches:

We have tested how LO 5.2 imports new ODF 1.3 features: fortunately it 
turned out that for most of the ODF 1.3 features, the standard namespace 
was already recognized in the import in addition to any extension namespace.
We don't consider commits where the feature itself is missing in the 
core, only those where the import filter can't recognize the new markup.
There are a few commits that can still be backported to 5.2 (which 
subset would be required for newer release branches is left as exercise 
for the reader):

* Unimplemented ODF 1.3 features:

We found just 2 new features that are not or only partially implemented 
in LO, and have filed enhancement bugs for these:

* OFFICE-2117 chart data-label-series
  https://bugs.documentfoundation.org/show_bug.cgi?id=133176
* OFFICE-3765 number:fill-character in number:text-style
  https://bugs.documentfoundation.org/show_bug.cgi?id=133200
* OFFICE-3941 user-index-entry-template links
  https://bugs.documentfoundation.org/show_bug.cgi?id=121842

Thanks to Samuel and Svante for helping with the ODF Toolkit parts, and 
Regina for carefully testing everything.

... that was all :)
