putting xml value into link in SSL

I have the following XSL fragment:

<xsl:template match="case">
<tr>
<xsl:apply-templates select="casenum"/>
<xsl:apply-templates select="severity"/>
</tr>
</xsl:template>


<xsl:template match="casenum">"
<td><a http://www.dev01.com/ViewCaseForm.asp?case_number=AAA"><xsl:value-of select="."/></a></td>
</xsl:template>

Where I show the AAA in the link I really want the value of casenum.

This will generate a link that is the casenum and when I click the link it will take me to the ASP application that gets that data for that case.

How do I get the value of the casenum inside the href tag? I'm sure it's simple but I can't figure it out.

I prefer to use AVT's (Attribute Value Templates)

<a href=http://www.dev01.com/ViewCaseForm.asp?
case_number={.}>Link Text</a>
