I was thinking of an extension to XSLT (I know, it's too late for this
version).

Something like:

<xsl:function name="reverse" namespace:fn="www.redrice.com">
	<xsl:param name="string" />
	<xsl:if test="$string">
		<xsl:value-of select="fn:reverse(substring($string,2))" />
	</xsl:if>
	<xsl:value-of select="substring($string,1,1)" />
</xsl:function>

so I could then call it with 

<xsl:stylesheet indent-result="yes" default-space="strip" 
	xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";
	xmlns:fn="www.redrice.com">

...

<xsl:value-of select="fn:reverse('able was I ere I saw Elba')" />

It hadn't occurred to me that the compactness of calling functions is
more important than the compactness of writing them, but it does seem to
be true.
