This is a well known issue and there's been ideas for a few CSS based 
solutions floating around to address it.  Specifically, the introduction 
of pseudo-classes or possibly pseudo-elements that would assist with the 
selection of headings or sections based on their outline depth.

In fact, some of the ideas were discussed yesterday in IRC.

Such captions could, however, be listed in a table of figures, which is 
commonly found in text books, usually after the table of contents. But I 
agree that using h1-h6 is not ideal for the other reasons you pointed out.
