For example, consider the following:

Lines 7 to 14 in 7e86a7f

	<section class="row td-box td-box--1 position-relative td-box--gradient td-box--height-auto">
	<div class="container text-center td-arrow-down">
	<h1>Vendors Supporting OpenTelemetry</h1>
	<span class="h4 mb-0">
	<p>Distributions and vendors who natively support OpenTelemetry in their commercial products.</p>
	</span>
	</div>
	</section>

Notice how the <span> contains a <p>, which isn't permitted. There are more such occurrences, search for <\w+ class="h4 for example.
