Re: Fast Infoset

For serializing, looks like you could use a SAX approach with the
XmlBean's  save(ContentHandler,LexicalHandler) method:

        OutputStream out = ...
        SAXDocumentSerializer saxOut = new SAXDocumentSerializer();
        saxOut.setOutputStream(out);
        myXmlBeanDocument.save(saxOut, saxOut); // both args ???
        out.close();
        
Haven't actually tried this so I don't know if it will work (or even
compile). But it seems like a reasonable approach based on the FI
samples and the fact that there isn't a save(XMLStreamWriter) method.

What you outlined for unserializing seems reasonable.
