In fact there has been some experimentation there. The 'description'
portion of DT schema can be RST. And the rest being structured data
could be transformed to RST. Grant did some experiments there. The
idea being to generate the DT spec from schema (rather than integrate
into the kernel docs). But not much progress there and it's not
something I'm spending time on ATM.
