Size of Fib objects

With the property "boundSize" it will be specified, that the size in bits for an Fib object should be stated. Although no vector elements exists for this property in the created Fib object, one vector element is generated when storing the object, also for the vector a domain is created in the root-element when storing (see section 21.2.4 on page ).

The vector element in a compressed format contains the number of bits, that the contained Fib object is long (including any checksums). If the Fib object is irreparably defective, in this way the beginning of the next Fib object can still be found and this Fib object can be restored. Without specifying the length of the Fib object $Obj_1$ the beginning of following Fib object $Obj_2$ in the data stream can probably not be determined, since it is unknown how long the elements of $Obj_1$ are. If $Obj_1$ is irreparably flawed, but the starting point respectively the starting bit of the next Fib object $Obj_2$ is known, then indeed the $Obj_1$ can not be displayed, but this will have no effect on multimedia information outside of $Obj_1$, so that the error is limited to $Obj_1$ .

The property of "boundSize" should best be used as the first / top element of a subobject in branch elements.
