Unescaping < and >

Is there any way of unescaping a "<" and ">" from a text() element. 
I'd like to
re-inject what is supposed to be xml, but is provided instead as escaped 
text within
document elements.

I've tried modifying the identity transform

	<xsl:template match="/ | @* | * | comment() | processing-instruction() | 
text()">
            <xsl:copy>
	    <xsl:apply-templates select="@* | * | comment() | 
processing-instruction() | text()"/>
             </xsl:copy>
        </xsl:template>

        <xsl:template match="document">
	     <xsl:variable name="xmlIntermediateText" 
select="translate(text(),'&gt;','>')"/>
                    <xsl:variable name="xmlText" 
select="translate($xmlIntermediateText,'&lt;','<')"/>
                    <xsl:value-of select="$xmlText"/>
        </xsl:template>
</xsl:stylesheet>

but the processor rejects the inclusion of '<' in the second argument to 
translate().
Thanks in advance,
Arthur
