https://www.w3.org/Bugs/Public/show_bug.cgi?id=27122

--- Comment #1 from Olli Pettay <bugs@pettay.fi> ---
"If either options' attributeOldValue or attributeFilter is present and
options' attributes is omitted, set options' attributes to true. "
should also check that attributeFilter has at least one value.
