Re: [whatwg] / not needed

The good thing on the picture element is that we have the possibility to serve 
other image-crops and with that the meaning could change so we could update the 
alt-attribute in the tag for every source-element. 
I do know this is a very special case but valid: An image displayed for a 
desktop while a monochrome display will get an drawing / shape-image instead. 
This has the very much same meaning but a different content and has to have a 
different description in alt-attribute IMO.

Another thing is: We do not have any graphic editor to do such things you have 
described yet. So you have to write this on your own along with SVG polyfills 
etc.
This is a valid solution but won't work for the masses of developers. Please, 
always think of the millions of HTML-developers who only want to do a normal 
cool website using responsive images.

Thanks!
