/** is a stream which allows writing the data of persistent objects.
    
    <p>Implementations of this service must fulfill the specifications of the 
    <type>DataOutputStream</type> service; futhermore, the stream needs to be chained to a 
    <type>XMarkableStream</type>. Therefore, it also provides the <type>XMarkableStream</type>
    interface, but it delegates the calls to the chained object.
    The written objects are held until this instance is destroyed.
    The references to the objects are written as four-byte integers 
    and begin at 1. Data format is written: </p>
    <pre>
    short   InfoLength
    long    ObjectReference // 0 indicates no object
    UTF     ServiceName     // length of 0 indicates this is only a reference
    long    ObjectLength    // 0 if it is a reference or no object, otherwise the len of the object data
    Object  ObjectData      // the data of the object
    </pre>
