Here is the bzipped patch and two new source files which are also needed. The changes to the DTD are attributes: defaultSerialization (database) and serialization (table) (java|xml, defaults to the existing Java serialization - BaseObject implements java.io.Serializable); and the attribute xmlElement (on a column) can be used to name an XML element explicitly (otherwise it uses the column name, with underscores removed and characters following underscores capitalised, remaining case unchanged).
The build obviously now also includes the betwixt jar. BaseObject now includes a couple of protected methods, getXMLIntrospector() and toXml(), in case you wanted to override the default behaviour in some way. It also provides methods to implement the Externalizable API, but doesn't actually declare itself to implement Externalizable (that is done by the generated Object). Generated Objects which are Externalizable also have a getElementDescriptor method which is used by the BaseObject to configure betwixt to generate correct XML for that object. Note that the externalizing is only one-way (out) at the moment. Using betwixt to construct data trees from XML is left as an short exercise for the reader ;-) Gareth
