// Description: This class represents an immutable pair of Strings (Name, Description) 
// That are generally used to represent name and description of an unsigned publish license 
// (a.k.a. template). Unsigned Publish License has property called LocalizedNameDescriptionDictionary
// which holds a map of a local Id to a Name Description pair, in order to support scenarios of 
// building locale specific template browsing applications.
//
// History:
//  11/14/2005: IgorBel :   Initial Implementation
