That RFC just describes the multipart/related MIME content type. What  
feature are you referring to?

What *is* something for the HTML WG, however, is to decide wether or  
not we should extend the syntax of some href and src attributes to  
accept references to attachments. Who else should make that kind of

I realize that everything that can be done with multipart responses  
can also be done with data URI's - at least in principle. The only  
problem is the size limitation and the reduced readability of the  
HTML document.

Generated content in server side applications:

If you want to ouput a image that is generated on the fly, say a  
clock or map something, you have to create a separate application  
that outputs that image. You then refer to the URL of that  
application in the src attribute of the img element.

Alternatively you may include the image by means of a data URI. What  
I suggest is to provide an opportunity to include it in an attachment  
and refer to that attachment in the src attribute.
