According to ? 9.1.4 Character references, "An ambiguous ampersand is
a U+0026 AMPERSAND (&) character that is followed by some text other
than a space character, a U+003C LESS-THAN SIGN character ('<'), or
another U+0026 AMPERSAND (&) character", text being "allowed inside
elements, attributes, and comments" (? 9.1.3 Text). (Should that be
"attribute values"? Either is probably acceptable.)
This text does not seem to define the ampersand in <element attr=&> as
ambiguous, but it still causes a parse error. <element attr=& attr2>,
<element attr="&"> and <element attr='&'> are all conforming, so the
most consistent solution would probably be to remove the parse error
by setting the "additional allowed character" to '>' when encountering
an ampersand in the "Attribute value (unquoted)" state.
Also, making the sequence "&<" conforming in (quoted) attribute
values, where the '<' occurs as text, seems inconsistent.
