    Use simple HTML5 DOCTYPE for about:legacy-compat
    
    HTML5 uses a DOCTYPE without a PUBLIC or SYSTEM identifier. It looks
    like this:
    
    <!DOCTYPE html>
    
    I can't use XSLT to output this, because to get a DOCTYPE I have to
    provide a PUBLIC or SYSTEM identifier. Luckily, the standards folks
    recognized this and provided this semantically equivalent form for the
    HTML DOCTYPE:
    
    <!DOCTYPE html SYSTEM "about:legacy-compat">
    
    But people don't like seeing the "legacy" identifier in their output.
    They'd rather see the shiny new DOCTYPE. Since we know that
    about:legacy-compat is defined by the W3C to be semantically equivalent
    to the sans-SYSTEM DOCTYPE, we could just special-case it in the HTML
    serializer in libxml2. So if you set the SYSTEM identifier to
    "about:legacy-compat", you get an HTML5 short-form DOCTYPE.
