generate_unique_html_dom_ids.xslt

<!-- this is how you generate unique DOM IDs in XSLT for use in generating HTML -->

<!-- generate the unique ID with "uid-" prefix and assign it to the uid variable -->
<xsl:variable name="uid">
  <xsl:value-of select="concat('uid-',generate-id(.))"/>
</xsl:variable>

<!-- now use the unique id to generate a <label>-<select> pair -->
<label for="{$uid}">Menu:</label>
<select id="{$uid}">
  <!-- etc... -->
</select>
