These replacements are used in include files at [https://github.com/plone/documentation/tree/6.0/docs/_inc](https://github.com/plone/documentation/tree/6.0/docs/_inc) with the name `_install-python-plone<##>.md` corresponding to the major and minor release number. These include files are in turn included in various parts of installation or development documentation, and should be checked to ensure the context makes sense.
