"Indicates that this is the defining instance of the enclosed term."
The way I understand it - and I may be wrong - would be something
like:

<dfn title="This is the definition">term</dfn>

Semantically, a bit like an inline, single item definition list. In
its application, similar to acronym or abbr, to expand the meaning of
a term (as opposed to an acronym or abbreviation, of course).

Topically enough, this was just mentioned over here
http://www.accessifyforum.com/viewtopic.php?t=2111

So, you'd have it when you have complex terminology that you'd like
to expand upon inline (although I'd much rather have something like
a separate glossary section, as I'm not convinced about support
for dfn in things like screenreaders - and even visual browsers, when
you're not hovering over a term with the mouse, don't normally expose
definition title attributes).
