In a declarative program you should aim to describe your output in terms 
of the input, not in terms of the processing steps used earlier.

So here you want to output two things, a list of strings all truncated 
to at most $n, and a list of strings that were longer than $n, so if 
$strings is your sequence of strings and $n is the limit on length

result:
<xsl:value-of select="for $s in $strings return substring($s,1,$n)"/>

these were truncated:
<xsl:value-of select="$strings[string-length(.) gt $n]"/>
