There's no explicit association between the two. That specific markup is
way too general.

Using <aside> is better than <div>.

Very good point. Aural web browsers, braille web browsers, other assistive
tools and parsing scripts (like search engines) would benefit from an
improved markup of associating captions to images.
That's why I came with the suggestion of <img caption="caption-element-id"
/>. It does not require the isolation of the image and caption in another
tag. Thus, the markup is less verbose, without losing the benefit of image
and caption elements association. Another benefit would be that the <img>
and <p> can both be optionally isolated with <aside>, <div> or anything
else (if the author considers this required, for styling or other
