It looks like a table to me. It's really a table with two columns, isn't
it?

That would be
<table>
  <tr><td scope="row">color</td><td>#000000</td></tr>
  ...
wouldn't it? And in a table, you could use various additional markup,
like <thead> with column headers in it, or <caption>, or
summary="...", etc.

Certainly. You would not define the term "color" but specify a value for
"color", and the reader must be assumed to already know what the term
"color" means. That is, you implicitly postulate the existence of a
definition, instead of giving one. Beware that what HTML specifications
say about <dl> is just great confusion - they first define it as a
definition list, and this is what he can reasonably regard as the
normative definition of the semantics, and then they go on and discuss and
show all kinds of stuff where <dl> is only used to get a particular visual
appearance (which browsers are expected to use, without really saying it,
and which is very poorly implemented in browsers, really).

<dl>, surely not. <table>, why not - this is an old debate, and there's
really no reason not to use <table> for tabular data like
(label, field) pairs. But you can also use just <div> and specify the

So what would be the point of defining a special element to be used for
two-column tables?
