Here is an example off the top of my head. Let's write a glossary of

<h1>A list of animals, loosely-defined</h1>

<dd>A mammal with four legs</dd>

<dd>Creepy-crawly with eight legs</dd>


Technically there is no link between "Dog" and its definition. We're used to
understanding that the three <dt> refer to the same <dd>, mainly because we
can read the language and the author hopes so, but no link is actually
provided, and it's not different, HTML-wise, from this:

(implied <dd> for a definition not written yet)

(implied <dd> for a definition not written yet)

<dd lang="la">Equus caballus</dd>

Hoping to have cleared things up.

The <di> would make it all explicit indeed by either grouping the three <dt>
or explicitly setting them apart.
