From the ARIA 1.1 draft:

----
A container for a collection of elements that form an image.

An img can contain captions and descriptive text, as well as multiple image files that when viewed together give the impression of a single image. An img represents a single graphic within a document, whether or not it is formed by a collection of drawing objects. In order for elements with a role of img be perceivable, authors must provide alternative text or a label determined by the accessible name calculation.
——

Thus, it is already a compound object, though the above description isn’t exactly what we have in mind for it.

Possibly nothing. A definite answer to that question would be helpful here.

Unfortunately I had to leave the call just as this part of the conversation was starting. Based on the mailing list discussion, though, my understanding is that “symbol” is meant to represent the same kind of object as “icon”, but the former is a component of an SVG document whereas the latter is the entire image that comprises the SVG document.

I don’t think the ARIA semantics should depend on whether or not an entity can occur as a component of a larger graphic, however. There may be other distinctions between the two that I’m not appreciating, though.
