Hi, I have the Schematron schema at the end of this email, which I think is correct. If I compile it myself using the SVRL and ISO skeleton for Saxon from http://www.schematron.com/, everything's fine and it seems to validate correctly my instances. But if I assiciate it directly to one instance (Associate Schema... action) it seems there is a problem at compile time: see the screenshot (sorry I didn't find where to look for the complete text error messages) at: http://www.fgeorges.org/tmp/oxygen-schematron-error.jpg So my questions are: 1/ where (how) is it possible to find the complete error messages, as text? and 2/ do you have any clue about that error?
