RE: [xsl] Expanding Ranges

["Michael Kay" <mike@xxxxxxxxxxxx>]

In XSLT 2.0 if you have the start and end of the range as integers $start
and $end, you can do

<xsl:value-of select="for $i in $start to $end return concat('fig', $i)"/>

In 1.0 you have to do a call on a named template that calls itself
recursively to process each number in the sequence.
