We hope to start using HTMLBook in a WordPress application where everything in between <div class="content"> tags is generated by WordPress.
This document is valid HTML5:
<!DOCTYPE html>
<head>
<title>HTMLBook Sample</title>
<meta name="HTMLBook Sample" content="text/html; charset=utf-8"/>
</head>
<body data-type="book" class="book" id="htmlbook">
<section data-type="chapter">
<header>
<h1>HTMLBook</h1>
</header>
<div class="content">
<h1>WordPress Post</h1>
<p>The User Is Doing Things</p>
<h1>WordPress Post</h1>
<p>The User Is Doing Things</p>
</div>
</section>
</body>
</html>
(Tested here: https://html5.validator.nu/)
The same document with an extra:
<html xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3.org/1999/xhtml ../schema/htmlbook.xsd"
xmlns="http://www.w3.org/1999/xhtml">
In the header is not valid HTMLBook. It complains about the second <h1>
element h1: Schemas validity error : Element '{http://www.w3.org/1999/xhtml}h1': This element is not expected."
I understand why it is invalid in HTMLBook but... the HTML5 spec "encourages" authors to use "headings of the appropriate rank" instead of h1 everywhere. An encouragement is not a normative requirement.
Is there something we can do to loosen the headings validation between a given div tag?
