Migration to Xalan 2.7.1

Hi,
I am a beginner on XSLT.
I have a template say, columnHeader which i am calling as below in a xsl:

<xsl:call-template name="columnHeader">
<xsl:with-param name="value"><a id="frameLoader"
href="javascript:void(0);" onclick="javascript:<xsl:value-of
select="$gridName"/>.expandAllTreeRows(this);">+</a></xsl:with-param>
</xsl:call-template>

Inside the template apart from other stuff, i print the value using
xsl:value as below:

<xsl:value-of select="$value"/>

This code was working fine before migrating to Xalan 2.7.1. But, once
i moved to Xalan 2.7.1, text in the value variable is getting printed
as raw text on the browser. It's not being treated as html and hence
not being rendered as a href in the browser.

Please suggest.
thanks,
ravi.
