I agree with Toby. What about modifying the rule to account for both:

If the "legend" class is found on the same element as the "image"
class (or the image inferred by the previous rule), then the contents
of the title attribute MUST be used as the legend. <new>If the title
attribute is missing or empty, the alt attribute MAY be used.</new>.
