> It would be useful to be able to add extension elements to the end of the Atom feed that's returned by a query (when using the AtomPub bindings). This would allow extra query-specific metadata to be returned in the response.
> For example: Alfresco uses Solr "under the hood" - by including extension elements in the Atom feed, extra information, such as faceting results, could be included in the feed.
> The class {{DiscoveryService.Query}} for the AtomPub binding currently passes a {{null}} as the final argument to the call to {{CmisService.query}}. If it passed an instance of {{ExtensionDataImpl}}, the implementer of the {{CmisService}} interface could populate the object with the extension elements. These could then be written out at the end of the feed.
> This update requires just a few changes to the {{DiscoveryService.Query}} and {{AtomFeed}} classes; I've attached an svn diff file with the changes.
