Still thinking how to change

             <xsl:apply-templates select="text()"/>
             

<xsl:template match="some_xpath/text()">
..

Into something where the text is concatenated in the face of PI's or
comments.

<xsl:variable name="temp">
<xsl:for-each select="text()"><xsl:value-of select="."/></xsl:for-each>
</xsl:variable>
<xsl:apply-templates select="$temp/text()"/>
