  | Improvements:
  |
  | 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. (see MNG-3626)
  |
  | 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 groupId/artifactId and sometimes version. It would be good to have them all extend one
  |   definition of these types

            The relative path of the parent <code>pom.xml</code> file within the check out.
            If not specified, it defaults to <code>../pom.xml</code>.
            Maven looks for the parent POM first 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.
            Set the value to an empty string in case you want to disable the feature and always resolve
            the parent POM from the repositories.
