You can't _just_ output attributes, do you mean that you want
an identity transform, but just don't copy attributes not in the
supplied list so in your example the output would be 

<customer> 
  <order> 
     <orderdet> 
       <item itemid="145" desc="hammer"/> 
       <item itemid="145" desc="nails"/> 
     </orderdet> 
  </order> 
</customer> 

as itemid and desc attributes get copied but id and qty do not?

if so take the identity transform example from the xslt spec and add
the template

<xsl:template match="@*" priority="10"> 
 <xsl:if test="contains(concat('|',$attr,'|'),concat('|',name(),'|'))"> 
  <xsl:copy-of select="."/> 
 </xsl:if> 
</xsl:template> 

then your 

<xsl:param name="attr" select"'itemid|desc'"/> 


should work.
