Defines the contract for Object XML Mapping Marshallers. Implementations of this interface
can serialize a given Object to an XML Stream.
Although the marshal method accepts a java.lang.Object as its first parameter, most Marshaller implementations cannot handle arbitrary Objects. Instead, a object class must be registered with the marshaller, or have a common base class.
