It strikes me that a user XSLT stylesheet could very readily produce
exactly this sort of structured textual view of title and description
elements, either as HTML or in some other format.  Borders and
indenting could be used to indicate nesting level. This could be
pretty generic/reusable.

Of course the UA would need to allow the option of applying a user
XSLT to create a derived view.
