maven2 offers an easy way for it's users to jumpstart a project called archetypes.
As xdoclet2 needs new users and maven2 needs new users and since it's easier to start a new project from scratch than convert and old one, this would help new dev's to start using both technologies. In substance, if anyone has a simple m2 pom that uses xdoclet2 and the basic files our community would appreciate if you could commit either as archetype or as the project structure. Someone will make the archetype for you.
Ideally one archetype per xd2 plugin, there is also a concept of partial archetype, but let's start gradually.
