Setting name attribute of <xsl:attribute>

Hi,

  I have what I hope is an easy issue to solve but my varying attempts to do so 
have not been successful. I have an xsl stylesheet which transforms some xml 
into another xml format.
  I only wish to generate XML in the output xml file if attributes in the src 
xml exist. At present I have a number of <xsl:if test......> directives to 
check if an attribute is present before processing.
  I would like to remove the need for the <xsl:if test......> and want to call 
a template to do the check and process if need be.....

  My template is 

      <!--
        Helper template that only pushes out out XML if value of attribute to 
publish is not null 
      -->
    <xsl:template name="checkAttributeNotNull">
        <xsl:param name="attributeName"/>
        <xsl:param name="attributeValue"/>
        <xsl:if test="$attributeValue">
          <xsl:attribute name="{$attributeName}">
              <xsl:value-of select="$attributeValue" />
          </xsl:attribute>
        </xsl:if>
    </xsl:template>

 And I call if via :

  
<xsl:call-template name="checkAttributeNotNull">
     <xsl:with-param name="attributeName" select="anAttName"/>
     <xsl:with-param name="attributeValue" select="anAttValue"/>
 </xsl:call-template> 

  The problem I have is within the template I call.  I cannot seem to set the 
name of the attribute I am trying to create with the parameter 'attributeName'. 
( i.e with <xsl:attribute name="{$attributeName}">)
 I have tried all sorts of combinations except for the correct one. I thought I 
could set this value at runtime ?????

Any pointers appreciated.

Thx
