We do this because we are defining a term and the <dfn> element is used for the defining instance of a term.
About the <dt> Element
The <dt> element represents the term, or name, part of a term-description group in a description list.
You can have multiple <dt> elements for each <dd> element.
You can also have multiple <dd> elements for each term too (if the same term matches multiple descriptions).
