plugin parameters and anything else.

 We once had a document that Vincent and I agreed upon and I was about to
 implement it and then I disappeared for 8 months so it never came to pass.

 So I guess it's important to figure out what people are using properties
 files for and see if we can't incorporate it all into the POM. Or if we do

                                </requireJavaVersion>
                                <requireNoRepositories>
                                    <message>Best Practice is to never define repositories in pom.xml (use a repository
                                        manager instead).
                                    </message>
                                </requireNoRepositories>
