I can suggest to use xsl:text with
disable-output-escaping="yes", though as discussed
many times the feature(d-o-e) is not supported by all
XSLT processors and must be avoided if possible.

However, to perform an identity transformation for
example, and put the result in the CDATA section, you
can do this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<xsl:output method="xml" indent="yes"/>
	<xsl:template match="/">
		<Message>
			<xsl:text
disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
				<xsl:apply-templates/>
			<xsl:text
disable-output-escaping="yes">]]&gt;</xsl:text>
		</Message>
	</xsl:template>
	
	<xsl:template match="node() | @*">
		<xsl:copy>
			<xsl:apply-templates select="node() | @*"/>
		</xsl:copy>
	</xsl:template>
</xsl:stylesheet>


But there is another potential problem here: in spite
of how you output(or generate) CDATA delimiters here,
the source XML can contain "]]>" sequence or even
during the transformation such sequence may be
generated and the result will not be well-formed
XML(CDATA section will contain forbidden "]]>"
sequence)...
