Like I mentioned in my previous email (sent only a few minutes ago),  
if other document languages are able to accept multiple tokens as a  
value for the ID attribute, and they can match an ID attribute via the  
# notation , then aren't we able to match a subset of ID values, in  
the same way we currently can with the class attribute in HTML?
