		<p>

			This sample shows how to configure CKEditor to output valid

			<a class="samples" href="http://www.w3.org/TR/html401/">HTML 4.01</a> code.

			Traditional HTML elements like <code>&lt;b&gt;</code>,

			<code>&lt;i&gt;</code>, and <code>&lt;font&gt;</code> are used in place of

			<code>&lt;strong&gt;</code>, <code>&lt;em&gt;</code>, and CSS styles.

		</p>

		<p>

			To add a CKEditor instance outputting legacy HTML 4.01 code, load the editor using a standard

			JavaScript call, and define CKEditor features to use the HTML compliant elements and attributes.

		</p>

		<p>

			A snippet of the configuration code can be seen below; check the source of this page for

			full definition:
