[sdx-users] xsl debugging

[Emmanuel Bégué]

=> existe-t-il un moyen de retrouver la ligne qui pose problème
depuis les descriptions d'erreur que je reproduis ci-dessous?
(sachant que ma feuille results.xsl fonctionne bien en local
et est même validée par le débogueur de xmlspy -- et que j'en
ai retiré tous les appels à des templates externes...)
