Removing a chapter from all translations

Hi, I'm not sure how many translators are on this list, but I find myself writing the same note on a lot of the PRs I've been making to translations in the process of fixing https://github.com/php/doc-en/issues/3579 which involves removing features/xforms.xml which is referenced in chapters/tutorial.xml. The reference to features.xforms has been removed from doc-en. The chapters/tutorial.xml remains because it is still referenced from manual.xml.in in doc-base and I didn't want to break every build. I've submitted PRs to every translation to remove the chapter and the reference to it. I'm going back and updating the PRs to update the revision tags on chapters/tutorial.xml. (Sorry, I hadn't caught up to that part of how the translations are managed. Very nice!) As the translations merge those PRs, that means they'll get built with the English version of that chapter. But once it has been removed from all translations, I'll go ahead and remove it from manual.xml.in and the doc-en repository, the entities in doc-base that only appear in that chapter, and it will finally be gone. The other reason I'm writing this for this list is to sort of document the process of removing a chapter from the manual while not causing any build failures: 1. Remove any references to it from doc-en. 2. Remove those references and the chapter itself from the translations. (Update the EN revision on updated files.) 3. Remove reference to it from doc-base. 4. Remove it from doc-en. 5. If there are any entities used only in that chapter, remove them from doc-base. Step 2 will be be more complicated if the references aren't a standalone paragraph like this case was, where it was easy to just the reference without having to actually understand any of the translations.
