Tanz,

As Trevor says, you need to set up an alternative sort, instead of scripting
exceptions to the alphabetic order of 'lang' attributes, which could get
quite clunky.
Trevor's method appends an f to every lang apart from ES which gets a t for
True, so it's always last alphabetically.

Another way would be to pass a parameter, or make a variable, holding the
ordered list of languages:
	<xsl:variable name="sortOrder" select="AR:CH:EN:FR:ES"/>
	<xsl:sort
	   select="string-length(substring-before($sortOrder, @lang))"
	   data-type="number"
	   order="ascending"/>
It's more flexible but you have to forsee all the @lang values that are
going to come up if you don't want ones that aren't in $sortOrder heading
your list.
