I suppose you meant
[dir="rtl"], [dir="rtl"] * { ... }
(since surely the rule should apply to an element that has dir="rtl" set on
it, even if it is not inside an element with dir="rtl").
But suppose we have
<div dir="rtl">
<div dir="ltr">
...
</div>
</div>
Then the rule would apply to the inner div, too. So things do get tricky,
especially considering the possibility that your style sheet may need to
deal with a document that has no directionality markup.
Of course many important special cases would still be manageable, like a
document with single directionality everywhere (most documents around,
undoubtedly) and a document with explicit dir markup for every element.
