XSLT: Xpath: sets: position()

Trying to get the first occurrence of an XML
element marked.  Can't be so difficult, can it?
Please - what am I doing wrong?

<xsl:template match="/SPC/*">
  <xsl:value-of select="name()"/>
  <xsl:choose>
        <xsl:when test="position()='1'">
          <H3><xsl:value-of select="@TITLE"/></H3>
        </xsl:when>
        <xsl:otherwise>
          <H4><xsl:value-of select="@TITLE"/></H4>
        </xsl:otherwise>
  </xsl:choose>
</xsl:template>

Thanks in anticipation,
lee
