/**
 * Generic RESTful server, which handles webservice access to arbitrary DataObjects.
 * Relies on serialization/deserialization into different formats provided
 * by the DataFormatter APIs in core.
 *
 * @todo Implement PUT/POST/DELETE for relations
 * @todo Access-Control for relations (you might be allowed to view Members and Groups,
 *       but not their relation with each other)
 * @todo Make SearchContext specification customizeable for each class
 * @todo Allow for range-searches (e.g. on Created column)
 * @todo Filter relation listings by $api_access and canView() permissions
 * @todo Exclude relations when "fields" are specified through URL (they should be explicitly
 *       requested in this case)
 * @todo Custom filters per DataObject subclass, e.g. to disallow showing unpublished pages in
 * SiteTree/Versioned/Hierarchy
 * @todo URL parameter namespacing for search-fields, limit, fields, add_fields
 *       (might all be valid dataobject properties)
 *       e.g. you wouldn't be able to search for a "limit" property on your subclass as
 *       its overlayed with the search logic
 * @todo i18n integration (e.g. Page/1.xml?lang=de_DE)
 * @todo Access to extendable methods/relations like SiteTree/1/Versions or SiteTree/1/Version/22
 * @todo Respect $api_access array notation in search contexts
