And in that regard, for what the Wiki page call 'layout or 
spacer', how about role="space" instead, to signify images which 
represent space, and therefore a space character as fallback?

Btw, is role=richtext smart? And where is role=text in the Wiki?

You link "richtext" to the fallback requirements, it could seem. 
But I think @role is linked to the very element. To explain why I 
think it is bad, consider XHTML 2, where e.g. an H2 element could 
contain an textimage, with the same text in the fallback.

	<h2 src=image>A little heading.</h2>

What role would that H2-image play then? Richtext? I guess no. But 
the moment I emphasized one word in the heading, then it should?

Richtext would also be easy to misunderstand, as many simply 
consider any format where bold, italics etc is /possible/ as rich 
text. I think role=text would be good enough.

But perhaps, instead, there should be a role to signify that 
something is embedded?
