[oXygen-user] Oxygen 11 installed, builds now failing

Here is the error messages as I can discern them: [java] Warning: at xsl:stylesheet on line 39 column 61 of i18n-postprocess.xsl: [java] Running an XSLT 1.0 stylesheet with an XSLT 2.0 processor C:\Program Files (x86)\Oxygen XML Editor 11\frameworks\dita\DITA-OT\demo\fo\build.xml:306: The following error occurred while executing this line: [[[there are several lines like this, followed by this entry:]]] C:\Program Files (x86)\Oxygen XML Editor 11\frameworks\dita\DITA-OT\demo\fo\build.xml:475: Java returned: 1
