I am attempting to use a babel code snippet to generate org headlines
for export. However, I seem to be running into a corner case here.

AFAICT, the only way to generate headlines safely with babel is to wrap
them in a :RESULTS: drawer.

Take the following example:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC perl :export results :results output org drawer
  print "* Headline One\n";
  print "* Headline Two\n";
  print "* Headline Three\n";
#+END_SRC
--8<---------------cut here---------------end--------------->8---

If I hit the source block, it creates wraps the output in a drawer. This
protects the results, so when executing the source block again, babel
correctly detects the drawer and replaces the output rather than
multiplying it indefinitely, as it does with "raw".

--8<---------------cut here---------------start------------->8---
#+RESULTS:
:RESULTS:
* Headline One
* Headline Two
* Headline Three
:END:
--8<---------------cut here---------------end--------------->8---

The problem with the results drawer is that org-element (and thus ox.el)
does not recognize it as a drawer and thus includes :RESULTS: in the
export. The html output looks like this:

--8<---------------cut here---------------start------------->8---
<p>
:RESULTS:
</p>
<div id="outline-container-sec-1" class="outline-2">
<h2 id="sec-1"><span class="section-number-2">1</span> Headline One</h2>
</div>
<div id="outline-container-sec-2" class="outline-2">
<h2 id="sec-2"><span class="section-number-2">2</span> Headline Two</h2>
</div>
<div id="outline-container-sec-3" class="outline-2">
<h2 id="sec-3"><span class="section-number-2">3</span> Headline Three</h2>
<div class="outline-text-2" id="text-3">
</div>
</div>
</div>
--8<---------------cut here---------------end--------------->8---

In short, is there a more graceful and export-friendly way to use babel
to generate org headlines for export? Or is there an easy way to get the
export backend to delete the opening part of the drawer (i.e.,
:RESULTS:)?

Any advice would be greatly appreciated. 

Thanks,
Matt
