Don't forget the Microsoft and the competing Open Office's twin XML formats.

Basically it's like a list of everything that was clean-sheet invented like ~ 1996-2007 used XML, then over the course of about 2 years it transitioned, and almost nothing invented after 2009 or so used it. It was like the whole software industry realized what a huge mistake and pivoted to JSON, all at once.

I should have clarified I meant XML is no longer seriously considered for any new protocols/formats.

For XML, we can add docx/xlsx/pptx/odt/ods/odp to the list.
