It's not relevant to this list but at the moment I have stability problems with my Ubuntu on an USB key.
I'll move back to Mandriva with was more stable on an USB key used with different PCs.

So if I understand your instructions correctly:
- install the Java JRE (obviously for SaxonJ under linux)
- install Xerces
- if Saxon still complains about using gnu.XML.SAXParser (I didn't try under Mandriva), use the class you mention.

As I'm a total newbie about Java (and at the moment not a lot of time to learn about it), is the package you mention (org.fasb.xerces) already part of Xerces and I just add -x SchemaValidatingCatalogResolvingXMLReader to Saxon,
or do I have to type somewhere the classes you give as examples?

Best regards.

Here is a sample class that I use with SaxonB V9 to get to both Xerces schema-aware parsing and catalog resolution. Just specify it as the class name on the -x parameter to Saxon:

--- start of SchemaValidatingCatalogResolvingXMLReader.java ---
package org.fasb.xerces;

import org.apache.xml.resolver.CatalogManager;
import org.apache.xml.resolver.tools.ResolvingXMLReader;
import org.xml.sax.SAXNotRecognizedException;
