Document "implementation-defined" behavior for LibreOffice

Hi all,

I have started page https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_implementation-defined_items

The ODF standard contains parts, which are "implentation-defined". That means,
<quote>
Implementation-defined is used in this standard for values or processing that may differ between ODF implementations, but is required to be specified by the implementor for each particular ODF-implementation.
</quote>
see https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_implementation-defined_items#cite_ref-1

And this
<quote>
2.3.2 OpenDocument Extended Producer

An OpenDocument extended producer is a program that creates at least one conforming OpenDocument extended document, and that meets the following additional requirements:

     A)It shall be accompanied by a document that defines all implementation-defined values used by the OpenDocument extended producer.

     B)It should be accompanied by a document that defines all foreign elements and attributes used by the OpenDocument extended producer.
</quote>

The foreign elements and attributes are documented in https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_OpenFormula_Extensions

A list of implementation-defined values was missing. Therefore I have started this page. But currently this page has no content. It lists only all parts where the standard specifies, that something is "implementation-defined". So help is appreciated, to fill it with content.

For implementation-defined items in functions I have linked to the help. But I have not verified, whether the help has indeed the needed information.

I have not used a table, because a table is hard to read in edit mode.

I have added the section numbers of ODF 1.2. When ODF 1.3 is out, new section numbers need to be added then.

Kind regards
Regina

Should not do things in the night. Some links are wrong.
Specification is https://www.oasis-open.org/standards#opendocumentv1.2

LibreOffice foreign elements are in https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_Extensions

Kind regards
