SVG Tiny 1.2 :: x/y attributes in svg element
It looks like Illustrator believes that x/y are valid attributes for the 'svg' element when exporting as Tiny 1.2. Based on reading the spec, I'm not entirely sure this is true.

Certain users of Illustrator, reporting into those responsible for corporate identity, are going to want built in support for SVG Tiny 1.2, and in particular the BIMI flavor. It would be great to see this feature implemented!
