Parse tags other than headings and `<p>`, e.g. definition lists

[melat0nin]

I'm thinking specifically of definition lists, i.e. <dt>s and their associated <dd>s. Using Nutshell to refer to definitions of terms that are presented in a semantically correct way seems very much to fit with the ethos of the project!

For example, in the following code on the target page:

<dl>
<dt id="myfirstterm">My term</dt>
<dd>My term's definition lorem ipsum dolor sit amet consectetur adipiscing elit</dd>
</dl>

it would be great if this code could retrieve the definition in a Nutshell:

...when we talk about [:my term](/terminology/#myfirstterm), what matters is...

I just came across this need as well - I could rework my content to use headers but I do think being able to reference definitions is a coherent usage of Nutshell.
