This is incorrect. If you omit an attribute's value it becomes the
empty string. See this testcase:
<!DOCTYPE html>
<body foo>
</body>
<script>
alert(document.body.getAttribute('foo'));
</script>
(In SGML languages, omitting an attribute's value was *actually*
omitting the attribute name, and the name was inferred from looking in
the DTD for what attribute had that as a possible enumerated value.
This is why XHTML1 requires boolean attributes to be written as
foo='foo'. XHTML5, though, prefers the form foo='', as that makes the
value identical to what it would be as an HTML boolean attribute.)
