//! Defines resources for an "Undefined Entity" : such an Entity
//! is used to describe an Entity which complies with the Norm,
//! but of an Unknown Type : hence it is kept under a literal
//! form (avoiding to loose data). UndefinedContent offers a way
//! to store a list of Parameters, as literals or references to
//! other Entities
//!
//! Each Interface must provide one "UndefinedEntity", which must
//! have same basic description as all its types of entities :
//! the best way would be double inheritance : on the Entity Root
//! of the Norm and on an general "UndefinedEntity"
//!
//! While it is not possible to do so, the UndefinedEntity of each
//! Interface can define its own UndefinedEntity by INCLUDING
//! (in a field) this UndefinedContent
//!
//! Hence, for that UndefinedEntity, define a Constructor which
//! creates this UndefinedContent, plus access methods to it
//! (or to its data, calling methods defined here).
//!
//! Finally, the Protocols of each norm have to Create and
//! Recognize Unknown Entities of this norm
