+ignore it. That means that when your configuration information is in

+considerably between FOP 0.20.5 and FOP 1.0 and its beta versions. Did
+you convert your file to the new format?</li>
+
+		<li>The FOP distribution contains a schema for configuration
+files, at src/foschema/fop-configuration.xsd. Did you validate your
+configuration file against it? Add the following schema location to

+
+and run the configuration file through a validating schema
+parser. Note that the schema cannot detect all errors, and that it is
+stricter about the order of some elements than FOP itself is.</li>
+
+		<li>Run FOP in debug mode (command line option
