I'm wondering, do we *really* need to add a srcset attribute to the <source> element when used with <picture>? Can't we just reuse @src and say it takes an "image candidate string" [1].

The advantages of just using <source>'s src attribute are:

1. we don't need to add a new attribute to <source>. 

2. we avoid conflicts and confusion between @srcset and @src on <source>.

3. The 'image candidate strings' are a superset of valid URLs anyway, so it does not affect backwards compat.

4. the <source> element outside the context of <audio> and <video> does not mean anything in legacy/current HTML5 UAs - hence, we are free to reinterpret it slightly in the new context.

WDYT?
