If you use a DOCTYPE that puts Explorer 6 in standards compliant mode, some properties

properties still belong to document.body. Checking if the documentElement exists is not 
enough, since it exists in all W3C DOM compatible browsers, so we also have to see if 
it has the property we are trying to access.
