Sorry. I'll keep that in mind.

Hum. I am still not clear why this is called implicitly with {} but I
need to call explicitly string-joing before normalize-space.

I replaced it with:

<xsl:template match="@*">
<xsl:attribute name="{name()}" select="normalize-space(.)"/>
</xsl:template>

Running the xsl code still leave whitespace at end/beginning of my
output strings:

Am I missing something ? I'd like to avoid duplicating the string-join
+ normalize-space all over my xsl code.

Thanks a bunch,
