That's strange, when i was a ping-pong player, matches ended at 21!
Taking a quick look at your code, i recall someone saying that
frequetly uses of xsl:call-templates and xsl:for-each was a sign of a
not-well designed transformation, it seems to indicate the author is
"thinking procedurely", that it's not the "way" to think in xslt,
where one should think "declarativly"... Or something like that...
I don't have my xslt tools here, but by monday i can test you xslt and
suggest some changes, if you don't solve your problem till there...
