      # this has been modified after the page has been loaded. More exactly, this method will return
      # the value of the given attribute, unless that attribute is not present, in which case the
      # value of the property with the same name is returned. If neither value is set, nil is
      # returned. The "style" attribute is converted as best can be to a text representation with a
      # trailing semi-colon. The following are deemed to be "boolean" attributes, and will
      # return either "true" or "false":
      #
      # async, autofocus, autoplay, checked, compact, complete, controls, declare, defaultchecked,
      # defaultselected, defer, disabled, draggable, ended, formnovalidate, hidden, indeterminate,
      # iscontenteditable, ismap, itemscope, loop, multiple, muted, nohref, noresize, noshade, novalidate,
      # nowrap, open, paused, pubdate, readonly, required, reversed, scoped, seamless, seeking,
      # selected, spellcheck, truespeed, willvalidate
