Markup for revisions / comments

["Jose Gonzalez Gomez" <jgonzalez.openinput@gmail.com>]

Hi there,

Is there any kind of markup for specifying a comment during the revision of a document, keeping track of the author? I'm thinking about a docbook document that is sent for review, and reviewers write their comments, even answering to each other. Is this possible to do with docbook? I know about remark, but don't know if this may be used in combination with some other tag.

Thanks in advance, best regards
Jose
