RE: [xsl] Output as per the filter is missing

In XSLT 1.0, if you do <xsl:value-of select="xxx"> and xxx selects more than
one node, only the first node in the set is output. To iterate over several
nodes, use xsl:for-each or (better) xsl:apply-templates.

You are doing <xsl:for-each select="section">, but that's rather pointless
because there is only one section.

At this stage of the game, it's much better to get into the habit of using
apply-templates. Write a template rule for each element saying what you want
done with it, for example

<xsl:template match="para">
  <xsl:apply-templates/>
</xsl:template> 

<xsl:template match="section">
  <xsl:apply-templates/>
</xsl:template> 

<xsl:template match="message[@priority='warn']">
  <p><xsl:value-of select="."/></p>
</xsl:template> 

<xsl:template match="message[@priority='info']">
  <xsl:comment><xsl:value-of select="."/></xsl:comment>
</xsl:template>
