Re: Let every element have a src attribute

In order to avoid having to mess with a bunch of related attributes as 
with "href", I'd allow "src" (or "data"?) and "type" only. I'd see it as 
a <object> shorthand, thus it should behave the same when it comes to 

Note that by "every element", I mean those who can have visible child 
nodes. This way you automatically exclude elements that have a src 
attribute today.

That's all a bit tricky though, as it implies inconsistencies. E.g. <img 
src="foo.png" alt="foo"> would differ from <span 
src="foo.png">foo</span> in some non-obvious ways.
