if I'm producing text or html or something I use the position()=1 method
(often as not). If I'm producing a proper structured xml nnested output
then you can't put the heading inside the loop as you need to do
something like

<xsl:if test="key(...)">
<section>
<head>...</head>
<xsl:for-each select="key(...)">
...
</xsl:for-each>
</section>
</xsl:if>


or since i see you're xslt2, you can often replace the whole shebang with

<xsl:for-each-group select="something" group-by="something else">
<section>
<head>...</head>
<xsl:for-each select="current-group()">
...
</xsl:for-each>
</section>
</xsl:for-each-group.
