I'd recommend populating it with a URL referencing a page that contains
a copyright notice for the embedded file.  I link to a license is nearly
worthless -- anyone can add such a link to any image and there is no
telling who did it or whether the image is actually licensed.

I've updated http://wiki.creativecommons.org/Exif to reflect this.

I think you mean XMP.  There is another similar recommendation, see
http://wiki.creativecommons.org/XMP

You could also populate XMP if the library you are using makes it easy
to do so.

Good point.  Comment sounds fairly unusable.
