Currently AnyService (and its derivative, providing REST services for users, groups and any objects) defines CRUD methods for the whole entities, e.g. allows to create, update, read and delete users, groups and any objects.
Inspired by the OData standard, new REST endpoints can be defined so that the following calls are allowed.
Returns the list of plain attributes for user 157 (DERIVED and VIRTUAL can also be used) with values.
Returns the list of values for the firstname plain attribute of user 157.
Adds or replaces the list of values for the firstname plain attribute of user 157.
Removes the plain attribute firstname from user 157.
