I'm trying to format to PDF an xml file both using the standard Oxygen scenario and a customization of mine. I always keep receiving message errors like these: 1. SystemID: C:\Users\Claudio\Documents\storicamente_lavorazione\Quaderni del territorio 2\Callari Galli\callariGalli.xml Scenario: Docbook PDF XML file: C:\Users\Claudio\Documents\storicamente_lavorazione\Quaderni del territorio 2\Callari Galli\callariGalli.xml XSL file: C:\Program Files\Oxygen XML Editor 13\frameworks\docbook\xsl\fo\docbook_custom.xsl Engine name: Apache FOP Severity: error Description: The process 'Apache FOP' ended with code: 1. The error was: ERROR - Couldn't find hyphenation pattern it Then I canceled out all xml:lang="it" 2.

I think there is something in the xml file that doesn't work properly ..... It was pasted using the smart option from a word file directly to the author editor. 3.
