 | 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 <code>&lt;project&gt;</code> element specifies various attributes 
         about a project. This is the root element of the project descriptor. 
         The following table lists all of the possible child elements. Child 
         elements with children are then documented further in subsequent 
         sections.

            The current version of the Maven project descriptor. This version

            should not be changed after the descriptor has been created. Maven 
            will update it automatically.

            <p>
              This element describes all of the dependencies associated with a
              project.  Each dependency is described by a
              <code>dependency</code> element, which is then described by
              additional elements (described below).
            </p>
            <p>
              These dependencies are used to construct a classpath for your 
              project during the build process.
            </p>
            <p>
              Maven can automatically download these dependencies from a 
              <a href="/user-guide.html#Remote%20Repository%20Layout">remote repository</a>.
            </p>
            <p>
              The filename that Maven downloads from the repository is 
              <code>artifactId-version.jar</code> where <code>artifactId</code> 
              corresponds to the <code>artifactId</code> element and 
              <code>version</code> corresponds to the <code>version</code> element.
            </p>
            <p>
              When Maven goes looking for a dependency in the remote repository, 
              it uses the dependency element to construct the URL to download 
              from. This URL is defined as:
            </p>
            <div class="source">
              <pre>${repo}/${groupId}/${type}s/${artifactId}-${version}.${type}</pre>
            </div>
            <p>
              Where
            </p>
            <dl>
              <dt>repo</dt>
              <dd>
                is the remote repository URL specified by 
                <code>${maven.repo.remote}</code>
              </dd>
              
              <dt>groupId</dt>
              <dd>is taken from the dependency element</dd>
              
              <dt>type</dt>
              <dd>is taken from the dependency element</dd>
              
              <dt>artifactId</dt>
              <dd>is taken from the dependency element</dd>

        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.

              Optional.  The source configuration management system URL

              from specific ID.

            <p>
              The format of this element is as follows:
            </p>
            <pre>scm:&lt;provider&gt;:&lt;provider-parameters&gt;</pre>
            <p>For cvs, the format for pserver repositories should be:</p>
            <div class="source">
              <pre>scm:cvs:pserver:user@host:/cvs/root:module-name</pre>
            </div>
            <p>
              For local networked repositories (eg. pserver to local machine)
            </p>
            <div class="source">
              <pre>scm:cvs:lserver:user@host:/cvs/root:module-name</pre>
            </div>
            <p>
              For ssh access:
            </p>
            <div class="source">
              <pre>scm:cvs:ext:user@host:/cvs/root:module-name</pre>
            </div>

            Remember that CVS will expect an environment variable called
            <code>CVS_RSH</code> to be set, typically to <code>ssh</code> or your
            ssh client.
            
            <p>
              Some cvs clients support other protocols, such as ntserver and extssh.
              Here's an example using CVS NT and ntserver:
            </p>
            <div class="source">
              <pre>scm|cvs|ntserver|user@server|e:\cvs|Deployment</pre>
            </div>
  
            Note the use of the vertical bar as delimiter as the repository has a 
            colon (<code>:</code>) in it.
            
            <p>
              For local file system repositories
            </p>
            <div class="source">
              <pre>scm:cvs:local:ignored:/cvs/root:module-name</pre>
            </div>
  
            <p>
              For StarTeam access: 
            </p>
            <div class="source">
              <pre>scm:starteam:username:password@host:port/project/view/folder</pre>
            </div>

            All of this information can be had from either the StarTeam Universal 
            Client (Tools-&gt;Server Administration-&gt;Server Properties) or from the 
            administrator. 
            
            <p>
              The delimiter is determined by the character after "scm". eg.
              <code>scm|cvs|pserver|user@host|/cvs/root|module-name</code> 
              is equivalent to that listed above. This can be useful for Windows users
              who have : in their cvsroot parameter (eg. D:\cvsroot)
            </p>
            <p>
              Where <code>pserver</code> is the protocol used to access CVS,
              <code>user@host</code> is the user name to log in to the specified
              cvs <strong>host</strong>, <code>/cvs/root</code> is the cvs root
              directory, and <code>module-name</code> is the name of the cvs
              module to be worked on
            </p>

            <p>As an example, the settings for an Apache project are usually:</p>
            <pre>scm:cvs:pserver:anoncvs@cvs.apache.org:/home/cvspublic:module-name</pre>
            
            <p>
              Currently CVS, Starteam and  SubVersion are the only supported scm's.
              Others will be added as soon as possible
            </p>
