Elements to attributes

Hi

I want to transform a list of attributes (NMTOKENS) into element. I.e. from:
 <foo N="PU US UK"/>
to:
<foo><St>PU</St><St>US</St><St>UK</St></foo>

The following:
<xsl:template match="foo">
<foo
        <xsl:variable name="wlista" select="@N"/>
        <xsl:variable name="st">
          <xsl:call-template name="lists">
            <xsl:with-param name="wlist" select="$wlista"/>
            <xsl:with-param name="tag" select="'St'"/>
          </xsl:call-template>
        </xsl:variable>
        <xsl:value-of select="$st"/>
</foo >
</xsl:template>

<xsl:template name="lists">
  <xsl:param name="wlist"/>
  <xsl:param name="tag"/>
  <xsl:variable name="wlistb" select="concat(normalize-space($wlist),' ')"/>
  <xsl:choose>
    <xsl:when test="$wlistb!=' '">
      <xsl:variable name="first" select="substring-before($wlistb,' ')"/>
      <xsl:variable name="rest" select="substring-after($wlistb,' ')"/>
      <xsl:call-template name="lists">
         <xsl:with-param name="wlist" select="$rest"/>
         <xsl:with-param name="tag" select="$tag"/>
      </xsl:call-template>
      <xsl:value-of
select="concat('&lt;',$tag,'&gt;',$first,'&lt;/',$tag,'&gt;')"/>
    </xsl:when>
  </xsl:choose>
</xsl:template>

Converts it to:
<foo>&lt;St&gt;UK&lt;/St&gt;&lt;St&gt;US&lt;/St&gt;&lt;St&gt;PU&lt;/St&gt;</
foo>


Please,

1. How can I replace &lt; and  &lt; with < and > in the ouput.
