Editing Elixir/HTML dump scraper (section)

=== References are simple in HTML ===
Once the wikitext is fully rendered to HTML, we can finally see all of the footnotes which were produced.  They appear something like this, <code><nowiki><div typeof="mw:Extension/ref">Footnote text.</div></nowiki></code>

Since the rendering is complete, we know exactly which references are visible, which is better than the ''potential'' references that we might have been able to determine from a static analysis of each template.

Template expansion also maps to HTML hierarchical structure, which makes it possible to tell when a reference was produced by templates or when a reference contains templates.  Both of these cases are interesting to our research.
