/Changes array
(Optional) An array of three integers that shall specify changes to the document that have been made between the previous signature and this signature: in this order, the number of pages altered, the number of fields altered, and the number of fields filled in. The ordering of signatures shall be determined by the value of ByteRange. Since each signature results in an incremental save, later signatures have a greater length value.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
