Extension point defaultRendition

Defines the default rendition of a given document. Contributions are of the form:

    <defaultRendition>
        <script language="JavaScript">
            function run() {
              if (CurrentUser.getName() != "bob") {
                return null;
              }
              if (!CurrentUser.getGroups().contains("members")) {
                return 'aRenditionName`;
              }
              if (Document.getPropertyValue("dc:format") != "pdf") {
                return 'pdfRendition';
              }
              if (Reason == "download" || doc.getType() == "Picture") {
                return 'watermarkedImageRendition';
              }
              return 'aDefaultRendition';
          </script>
    </defaultRendition>

The language can be any JVM scripting language, the default is "JavaScript".

The script must define a "run()" function that returns a string which is the name of the rendition to be used. The method will get called with the following global context (some values may be null): Document (DocumentModel) CurrentUser (NuxeoPrincipal), Reason (String), Infos (Map).
