Tuscany object model does not handle unknown content in composite files.

Tuscany object model does not handle unknown content in composite files.

Unknown content in composite files are not persisted when the Tuscany model is loaded. As a result, the unknown content is lost when I write the composite back to file.

As an example, say I don't include the Tuscany models which model EJB bindings. If I load a composite file which contains EJB bindings and write it back to file, I lose all of my EJB bindings. In this example, there's no expectation to work with the EJB bindings via the Tuscany model in a "first class way". Perhaps some generic get/set/edit methods but at the very least, persist the content of the EJB bindings in the Tuscany model and write them back out to file.
