namespace prefix problem

[de...@compchemcons.com]

Hi, 

I am reading a XML-Schema which itselfs imports other schemas.

The schema looks like:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema targetNamespace="http://www.cdisc.org/ns/odm/v1.2" 
           xmlns="http://www.cdisc.org/ns/odm/v1.2"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
           xmlns:xml="http://www.w3.org/XML/1998/namespace" 
           xmlns:sas="http://www.sas.com/xml/schemas" 
           elementFormDefault="qualified" attributeFormDefault="unqualified">
    <!--
          import ODM foundation schemas
      -->
    <xs:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="xml.xsd"/>
    <xs:import namespace="http://www.w3.org/2000/09/xmldsig#"   schemaLocation="xmldsig-core-schema.xsd"/> 
    <!-- include here any vendor extensions -->
    <xs:include schemaLocation="sas-extension.xsd"/>
</xs:schema>

Now, for a reason nothing to do with XMLBeans, I need the prefixes that were used in the schema for each of the namespaces. I realize the prefixes are nothing fixed, one could use others, but I would like to know them anyway.
>From the mailing list, I found some information that getting the prefixes was not possible in XMLBeans 1.X, and I wander whether it is possible to retrieve them in 2.0.
With my current code, I do not see them when e.g. using 
SchemaProperty[] attributes = sge[i].getType().getAttributeProperties();

So my question is: is it possible to retrieve the used prefixes with XMLBeans 2.0 ?

Part of my current code is below.

With best regards

=============

List sdocs = new ArrayList();
XmlOptions xmloptions = new XmlOptions();
xmloptions.setLoadLineNumbers().setLoadMessageDigest();
xmloptions.setCompileDownloadUrls(); // allow compilation of schemas that are imported/included using a URL
// xmloptions.setSaveNamespacesFirst();  // just trying, 30.8.2005
try {
	sdocs.add(XmlObject.Factory.parse(schemaFile, xmloptions));
} catch (Exception e) {
	System.err.println( schemaFile + " not loadable: " + e );
	String errormessage = "Could not read the Schema File:\n" + schemaFile.getAbsolutePath();
	JOptionPane.showMessageDialog(new MyJFrame(),errormessage);	
	OK = false;		
}
if(OK == true) {
	XmlObject[] schemas = (XmlObject[])sdocs.toArray(new XmlObject[0]);
	XmlObject mySchema = schemas[0];
	System.out.println("Schema validation gives : " + mySchema.validate());
	// compile the schemas
	SchemaTypeLoader sLoader = null;
	Collection compErrors = new ArrayList();
	XmlOptions schemaOptions = new XmlOptions();
	schemaOptions.setCompileDownloadUrls(); // allow import of other schemas using URLs
	schemaOptions.setErrorListener(compErrors);
	try {
		if (schemas != null && schemas.length > 0) sts = XmlBeans.compileXsd(schemas, sLoader, schemaOptions);
	} catch (Exception e) {
		if (compErrors.isEmpty() || !(e instanceof XmlException)) {
			e.printStackTrace(System.err);
		}
		System.out.println("Schema invalid:" + (partial ? " couldn't recover from errors" : ""));
		for (Iterator i = compErrors.iterator(); i.hasNext(); )	System.out.println(i.next());
		String errormessage = "Invalid ODM Schema \n" + "could not convert Schema to ODM elements";
		JOptionPane.showMessageDialog(new MyJFrame(), errormessage);
		OK = false;
	}
}
