Footnotes: Using a section without heading causes validation errors

[danielfdickinson]

goldmark/extension/footnote.go

Line 579 in 829d874

tag := "section"

causes

| 175 | <section class="footnotes" role="doc-endnotes"> <hr> | Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections. |

There does not appear to be a way to configure the tag to use (e.g.) 'div' when using HTML5. I'm probably missing something, but I don't see a way to override this without changing footnote.go source file.

I do note that in the referenced https://michelf.ca/projects/php-markdown/extra/#footnotes that the example output given is

<p>That's some text with a footnote.
   <sup id="fnref:1"><a href="#fn:1" class="footnote-ref" role="doc-noteref">1</a></sup></p>

<div class="footnotes" role="doc-endnotes">
<hr />
<ol>

<li id="fn:1" role="doc-endnote">
<p>And that's the footnote.
   <a href="#fnref:1" class="footnote-backref" role="doc-backlink">&#8617;</a></p>
</li>

</ol>
</div>

which uses a div (but also looks like the XHTML version).

For what it's worth here are some articles on the status of outlines (sections) and headings:

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Heading_Elements#multiple_h1_elements_on_one_page points to

Computer says no to the HTML5 outline
A decade + a year of heading backwards

Basically, it's a mess of spec that was never implemented and never updated to reflect implementation.

I can confirm this HTML validation warning using this short example based on Hugo: test page | HTML validator page
