CDATA in HTML title

<title>A Tutorial: <![CDATA[<!-- HTML Comments -->]]></title>

Use a CDATA section to escape text containing the comment delimiters (<!--) in text content so that it appears for all browsers. Otherwise comments should not be coded inside a <title> tag. (See the issues with HTML 5 comments.)

CDATA with ]]>

<![CDATA[... ]]]><![CDATA[]> ...]]>
<![CDATA[... ]]]]><![CDATA[> ...]]>

Since the characters ]]> terminate a CDATA section, those characters must be split into two different CDATA sections.
