    Subject: Bug when interpreting attribute values
    
    I have chosen not to subscribe to this list. I just want to convey to 
    you an issue regarding the W3C HTML Validator:
    
    It may be called a bug, but I am not sure. When validating the fragment
    <img src=/grafik/layout/read_more.gif alt="Read more">
    
    the Validator reports an error: "an attribute value must be quoted if 
    it contains any character other than letters (A-Za-z), digits, 
    hyphens, and periods; use quotes if in doubt"
    
    The underscore is an issue here. But the HTML spec 
    http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.2 clearly 
    states that underscores are allowed without placing quotation marks. 
    Surely, I will place quotation marks around this URI, but I believe 
    there is a conflict here.
