[whatwg] Inconsistent behavior for empty-string URLs

Shouldn't this proposal take into account the CSS3 content property? (
http://www.w3.org/TR/css3-content/)

 E.g., figure[alt] { content: attr(href, url), attr(alt); }


This was discussed not too long ago, starting in this thread:
Adding a src attribute to all elements (
http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-November/023955.html
)
