For now DocBook Editor is a bit customized Visual Page Editor(see https://jira.jboss.org/browse/JBIDE-6600 ), which supported extra docbook tags. We have couple of issues to make it more lightweight. For example this one https://jira.jboss.org/browse/JBIDE-7058 .Also I have created an issue related to this post see https://jira.jboss.org/browse/JBIDE-7227 .Have you founded any other aspects of docbook editor working, CA,or smth else?
