The one fundamentally useful application I can see is having the
aggregator understand that RTL languages need to be wrapped in a
<div dir="rtl">. But as you pointed out, entries with multiple
languages will need that markup within them anyway...
It's more than this. Other Atom elements need to have some mechanism to
indicate direction, because aggregators will most likely try to "stitch" the
metadata together with the content. Consider, for example, an aggregator
that displays the <title> before the actual content -- you'd want the title
to be right-justified if it's primarily in RTL language.
