In the following output for a sample API notice how the "MODULE DESCRIPTION" label is within a <section> tag, so that trying to extract the module description based on the marker comments will yield a malformed <section>:

<div class="contentContainer">
<section role="region">
<!-- ============ MODULE DESCRIPTION =========== -->
<a id="module.description">
<!-- -->
</a>
<div class="block">This is module mA. This is more text for mA.</div>
</section>
<ul class="blockList">
<li class="blockList">
<ul class="blockList">
<li class="blockList">
<!-- ============ PACKAGES SUMMARY =========== -->
