The main problem with a global attribute is that it would make it less  
clear which attribute takes precedence and whether or not the value is  
resolved as a URL, as previously discussed. [1][2] Further, what would the  
global attribute be? value="" already exists with different semantics on  
<button>, <option>, <input>, <li>, <meter>, <progress> and <param>.  
content="" is not an option since RDFa uses it (in the early days  
microdata had both a property="" and an about="" attribute and there were  
objections to this).
