6This is the content of the alt tag of an image if the user had not
7previously specified an alt attribute.  This applies to all images without
8a valid alt attribute, as opposed to %Attr.DefaultInvalidImageAlt, which
9only applies to invalid images, and overrides in the case of an invalid image.
10Default behavior with null is to use the basename of the src tag for the alt.
