<!--
 |
 | 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 versioning of individual elements on the class level and the field level so that
 |   different versions of the model can be output.
 |
 | 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

        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.

    A sketch of what a plugin configuration might look like where
    we have plugin wide parameters that apply to all goals/mojos
    and goal/mojo specific parameters that will override any
    of the plugin wide definitions.

    At first the configuration element will be a flat set of properties
    but i would like the configuration to actually be an arbiitrary
    data model or a simple DOM like structure so that mojos can
    be arbitrarily configured in the same fashion plexus plugins
    are configured.
