RE: [xsl] wrap text

["Michael Kay" <michael dot h dot kay at ntlworld dot com>]

You are using a very old release of Saxon, and your first step should be to
upgrade to something more recent. The recommended version is now Saxon 6.5

You should also delete the line
<xsl:value-of select="$rest"/>
from your template. Apart from being incorrect, this stops tail recursion
working (though tail recursion probably wasn't implemented in the release
you are using anyway...)
