Re: All teidata.pointer attributes

Whoops I made a mistake in that message (I blame the Brisbane summer heat!)

The code I had inside the templates was wrong:

   <!-- wrong! -->
   <xsl:copy>
      <xsl:attribute name="haspointer">true</xsl:attribute>
      <xsl:copy-of select="@* | node()"/>
   </xsl:copy>

It should of course have applied templates to the children of the matched
elements:

   <xsl:copy>
      <xsl:attribute name="haspointer">true</xsl:attribute>
      <xsl:copy-of select="@*">
      <xsl:apply-templates/>
   </xsl:copy>

[turning the fan on now]
