File Structure
An object stream itself, like any stream, is an indirect object, and there must be an
entry for it in a cross-reference table or cross-reference stream (see Section 3.4.7,
the form

The generation number of an object stream and of any compressed object is
implicitly zero. If either an object stream or a compressed object is deleted and
the object number is freed, that object number can be reused only for an ordinary
(uncompressed) object other than an object stream. When new object streams
and compressed objects are created, they must always be assigned new object
numbers, not old ones taken from the free list.
