SVG with ARIA roles

[JAWS-test]

The SVG element can have the ARIA roles application, document, or img. Without ARIA roles, it has no implicit role. The SVG AAM specification applies when? Only if the SVG does not have an ARIA role or also with the roles application and document? I suspect that SVG AAM does not apply if role=img, because then all child elements implicitly have role=presentation. The question is, what is the AccName of an SVG with role=img? Does then https://www.w3.org/TR/accname-1.1/ apply?
