In the project there are any requested changes <chg-requests>. For each <chg-request> there is one or more related objects resp. object revisions (<chg-object-revision-ref>). The referred objects are the ones to be improved resp. causing the problem to be solved by the required change. Thus no <chg-request> can be there without respect to a <chg-object-revision>. If necessary a fake <chg-object-revision> should be introduced.
For each <chg-request> the following can be entered:

<long-name>
A working title for the change request. This can be used in verbal communication as well as anntoatin in overview reports
<short-name>
A label for the change request. This can be used to refer to link the document to Project Management Systems
<chg-keywords>
it is possible to enter blank separated keywords here. These can be used for retrieval purposes as well as in overview reports. It could also be used to enter notes for the project manager like assignments to indiviuals etc.
<chg-proposed-by>
can receive the names or initials of the individual(s) who proposed the change request.
<chg-priority>
Allows to qualify the priority of the requested changes. The priorization model is up to the author. The SGML processing system can use this element to order the requested changes according to their priority. Therfore the highest priority should be of low lexical order.
It can either be a simple number (high priorities get low values) determining the priority.
Another model is a letter/digit combination. The letter characterizes the importance, the digit the urgency (e.g. A 2 says very important and medium urgent)
<chg-class>
allows to classify the requested change. This element should receive something like enhancement error
<chg-related-objects>
This element receives links to the related object revidions. The semantic of this link is, that the referred object revision is causing the problem (e.g. with a bug report) or must be enhanced (in case of an enhancement request). All objects concerned by the change request should be mentioned.
<chg-subject>
This is the place to describe all the aspects of the change request. All paragraph level elements can be used.
<chg-reason>
This element receives the justification of the change request. In this element all problems should be mentioned which shall be solved by the requested change.
