Within one document, there are several <chg-objects> to be considered in the actual project domain. These objects can be any deliverable in the process, either documents, products or even libraries.
The development of <chg-object> takes place by creating new revisions. These <chg-object-revision>s are characteriezed by

<long-name>
receiving the work title of the revision (e.g. "Summer 95 release")
<short-name>
holding the revision number
<date>
holding the release date

The <chg-object-revision>s are referred to from within <chg-request>. This allows to generate <chg-object-revision> related tables and lists.
It is recommended not only to capture existing revisions but also future ones. This allows to refer them in order to receive complente release notes etc.
