XML? how is this not just XML with a schema?

It's from Microsoft. They always cook up their own incompatible shit instead of using existing standards.

Does XML allow you to define for-loops inside <bracketed> items then reference the loop variables inside {{template vars}}? https://youtu.be/b9WDcFsKixo?t=223

I guess it doesn't prevent you from doing such things, but... well... there's some eyebrow-raising shoehorning in this one.

Maybe it's not fully XML compliant.

Anyway quite an interesting project, XML's a better fit for "programmable" data.

XML, for those born after 1990, you could have well said COBOL or FORTRAN, something gramps used to mention.
