## Description

`RevHistory` is a structure for documenting a history of changes, specifically, a history of changes to the document or section in which it occurs.

DocBook does not mandate an order for `revision`s: ascending order by date, descending order by date, and orders based on some other criteria are all equally acceptable.

### Processing expectations

Formatted as a displayed block. A tabular or list presentation is most common.

The order of `revision`s within a `revhistory` (ascending or descending date order, for example) is not mandated by DocBook

### Future Changes

Due to a parameterization oversight in the DTD, `RevHistory` is allowed in some outlandish places. Still, it is not an inline, so it should not be used inside `LineAnnotation`s, `Link`s, or `Quote`s. (Not to mention the truly outlandish places like `Title` and `SeeAlso`!)

In a future version of DocBook, `RevHistory` will be removed from these inline contexts.

The original intent for `RevHistory` was simply to document the history of changes to the document that contains it. In keeping with this meaning, you are advised to limit its use to places where bibliographic meta-information is allowed (the “info” elements).

One can argue that `RevHistory` has broader applicability for documenting changes to other systems as well, and in light of this, it may become available in more contexts, but that has not yet been decided.
