    It is not valid in HTML 4: 

    <!ENTITY % html.content "HEAD, BODY">

<!ELEMENT HTML O O (%html.content;)    -- document root element -->
<!ATTLIST HTML
  %i18n;                               -- lang, dir --
  >

    It is not valid in XHTML 1.0:

    <!ELEMENT html (head, body)>
<!ATTLIST html
  %i18n;
  id          ID             #IMPLIED
  xmlns       %URI;          #FIXED 'http://www.w3.org/1999/xhtml'
  >

    It is valid in HTML 5:

    The following attributes are common to and may be specified on all HTML elements (even those not defined in this specification):

    • …
    • class
    • …

    My Oracle ADF application does this – wounder why

    Presumably to apply style or JS from a shared external file to specific pages.
