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.
