I understand it. If that schema defines a document format and document
format cannot be modified then I do not see how software that handles
that document format is free. Programmers should be able to improve
the format or make it incompatible as it is part of the overall
document creation. It is not software but data used by software. Data
should be modifiable in my opinion.

Let us say enriched mode in Emacs, if it would not be modifiable by
programmers who fork Emacs, I am not sure if Emacs would be free
software.

How about Org mode itself? If its format would not be modifiable, then
we would not have software similar on Org or based on Org mode, such
as:

OneModel — an Alternative to emacs org-mode
https://soylentnews.org/article.pl?sid=16/04/23/0149257

Maybe we would not have Orgzly as mobile Org mode application that is
not Emacs. Maybe there would be not Vim Org mode and so on.

I just hope that Libreoffice is not using non-free OASIS schemas.
