        <span class="tag-links">
          <xsl:variable name="tags" select="tagsLib:getTagsFromNode(@id)" />
          <xsl:choose>
            <xsl:when test="count($tags/tags/tag) = 0">
              Not tagged
            </xsl:when>
            <xsl:otherwise>
              Tagged:
              <xsl:for-each select="$tags/tags/tag">
                <a href="{umbraco.library:NiceUrl($currentPage/ancestor-or-self::RunwayBlog/@id)}?filterby={.}" rel="tag">
                  <xsl:value-of select="."/>
                </a>
                <xsl:if test="position() != last()">, </xsl:if>
              </xsl:for-each>
            </xsl:otherwise>
