DJabberd targets to be a Perl Toolkit for XMPP, from which you can build a solution, including communication server. As such majority of XEPs are implemented as external plugins. If some XEP is supported natively that's ususally done either as a show-case (limited functionality, should be extended by plugins) or as being necessary for normal functionality (eg. compatibility layer unlikely to be implemented as plugin).
Implemented either in core or in external plugins
