 | o add specification element to a field, this would be more a technical description of
 |   what is allowed in the field.
 |
 | o validators: there could be several levels of validation. Simple type validation could
 |   be done with a regex, but we need inter-field validation and rules which could be
 |   dealt with by something like drools.
 |
 | o i18n: would be good to be able to have names/descriptions/specifications
 |   in as many languages as possible.
 |
 | o annotation mechanism so that changes to the model can be accurately tracked.
 |
 | o need to clean up all the descriptions, matching anything to the current project-descriptor.xml file and
 |   improving on that
 |
 | o use enums where appropriate (eg dependency scope)
 |
 | o a number of elements have a grouId/artifactId and sometimes version. It would be good to have them all extend one
 |   definition of these types

            The type of dependency. This defaults to <code>jar</code>. While it usually represents the extension on
            the filename of the dependency, that is not always the case. A type can be mapped to a different
            extension and a classifier.
            The type often correspongs to the packaging used, though this is also not always the case.
            Some examples are <code>jar</code>, <code>war</code>, <code>ejb-client</code> and <code>test-jar</code>.
            New types can be defined by plugins that set
            <code>extensions</code> to <code>true</code>, so this is not a complete list.

        We could probably have a specific element for a dev mailing list for
        things like CI, and maybe even a specific element for the user and scm
        mailing lists. Then leave the more lose structure for any other type
        of mailing list.

            The relative path of the parent <code>pom.xml</code> file within the check out.
            The default value is <code>../pom.xml</code>.
            Maven looks for the parent pom first in the reactor of currently building projects, then in this location on
            the filesystem, then the local repository, and lastly in the remote repo.
            <code>relativePath</code> allows you to select a different location,
            for example when your structure is flat, or deeper without an intermediate parent pom.
            However, the group ID, artifact ID and version are still required,
            and must match the file in the location given or it will revert to the repository for the POM.
            This feature is only for enhancing the development in a local checkout of that project.
