[whatwg] image captions

Quoting David Walbert <dwalbert at learnnc.org>:
> For scripting purposes I have occasionally needed to tie an image and

If the relationship between the image and caption is well defined. For  
example, when the next sibling _element_ of <img> is <p>, <p> is the  
caption of <img> you can easily introduce some DOM attribute on  
HTMLImageElement named caption that gives you back the  
HTMLParagraphElement associated with it.
