34 * \brief Allows to validate the attribute value of a feature or the whole feature.
36 * This object is assigned by the name
37 * in the XML file to the specific attribute or to the whole feature.
38 * If validator returns "false", it is signalized in user interface
39 * and feature is not executed.
40 * Validators must be registered in the validators factory to be
41 * correctly identified by the XML string-ID.

56 * \brief Manages the registered validators
58 * Allows to get a validator by the feature identifier and
59 * the attribute identifier (if attribute is validated).
60 * All accessible validators mustbe registered by the ID string first.
61 * The instance of this factory can be get in the Session.
62 * Keeps the validator objects alive and just returns one of it by request.
63 * All the needed information is provided to the validator as an argument,
64 * this allows to work with them independently from the feature specific object.
