Draft an example and show us how it would look!  :-)  There is
absolutely nothing preventing us from expressing a DT in XML format,
or even using XSLT to define DT schema while still using our current
.dts syntax. It would be trivial to do lossless translation between
.dts syntax and xml.

The problem that I have with XML and XSLT is that it is very verbose
and not entirely friendly to mere-mortals. However, I'm more than
willing to be proved wrong on this point.
