xsl template parameter passing

I was wondering if anyone has done something similar to what I need done.

I have to show users an error whenever something goes wrong. I have a template such as this:

<xsl:template name="errorbox">
<xsl:param name="message" select="''" />
<div class="errorbox">
<h2><xsl:value-of select="$lang.NBoxError"/>:<xsl:text> </xsl:text></h2>
<div class="boxcontent">
<xsl:value-of select="$message"/>
</div>
</div>
</xsl:template>

this works fine if "$message" is only text. however, many times, a link needs to be included in the "message" portion. so i dont know how to call a template, and pass in the "body" of the message, which can contain html. and use xsl to generate that html. I've tried something like this, but does not work:

<xsl:call-template name="errorbox" >
<xsl:with-param name="message" >
<a>
<xsl:attribute name="href">URLTEXT</xsl:attribute>
Link
</a>
</xsl:with-param>
</xsl:call-template>

please help.

sounds like? <xsl:copy-of select="$message"/>

thank you. that was it!
