How to unescape XML characters with help of XSLT?

I need to unescape XML characters from inside of XML nodes with the help of only XSLT transformations. I have <text><>and other possible characters</text> and need to get it as valid formatted HTML when I place it inside of the body tag.

<xsl:template match="text">
  <body>
    <xsl:value-of select="." disable-output-escaping="yes" />
  </body>
</xsl:template>

Note that the output is not guaranteed to be well-formed XML anymore.

With xslt 2.0 I have come up with this one. Note that the output is not guaranteed to be correct xml, a simple unequality can mess up your output.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<xsl:character-map name="a">
    <xsl:output-character character="&lt;" string="&lt;"/>
    <xsl:output-character character="&gt;" string="&gt;"/>
</xsl:character-map>

<xsl:output use-character-maps="a"/>

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

I haven't found an answer to this question. So I came to the conclusion that this is no way to do this. I found workaround for this problem, unescaping file on server side.
