A non-trivial second dimension.  By recoding the <dl> as a <table> in
this way, you're saying that each row represents a group (reasonable),
and the first column is "key" while the subsequent columns are
"value".  That latter bit doesn't feel significant enough to me to
make it *actually* 2-dimensional; it just feels like it is squeezing
semantics into a shape that doesn't quite fit.

Because Hixie believes that the grouping of <dt>/<dd>s is sufficiently
defined in HTML and doesn't need an explicit structure to encode it.
Fantasai's offered some good arguments to the contrary that I wasn't
able to come up with on the spot when I was talking about it with
Hixie recently.  I've sent them over to him and we'll see if he thinks
it's convincing.
