    This part of the noticiation processing is done with WS Star notification.
    A profiling of the notification process shows that some improvements can be done on the read and write processes (Dom, JDom, Jaxb conversion for exemple, factory creation and so on).

Caution don't deprecate the DOM API because using a API based on Source generates a XML parsing. So if on the client side the XML is already parsed as DOM document, use the DOM API. Otherwise, if the XML is not parsed, use the Source API. Please add a note on the usage of each API.

An other optimization could be to deprecate the API using DOM Document and replace it by an API using a Source. See the attachment 'unmarshall-source.patch'

A first optimization is to used only one unmarshaller instead of created one when unmarshalling is needed. Caution to the concurrency on unmarshalling.
