I second Anne's opinion about a new attribute isContentEditable. Both  
Internet Explorer and Safari have implemented this already although  
Safari's support for inherit has a few bugs. It really is needed for  

The empty string indeed causes the element to be contentEditable in  
both IE and Safari. I'd suggest to make the element editable if the  
attribute value has the empty string.
