If this isn't generating any <a> elements, then key('ids',$id) isn't
selecting any nodes, and there's no way of telling why without seeing your
key definition and your source document.

incidentally, you could rewrite the above as

<xsl:template name="x">
 <xsl:param name="id" select="1" />
 <xsl:for-each select="key('ids', $id)">
   <a href="{id}"><xsl:value-of select="title"/></a>
 ...
</xsl:template>

which some people would find more readable...
