/**
 * Generator with specified attribute types.
 *
 * @subsection AGeneratorOverview Overview
 *
 * The TaGenerator takes four template parameters to specify attribute classes for
 * the global attribute and state-, event- and transition-attributes. 
 *
 * In the context of a TaGenerator, attributes still have only minimal sematics: they can be 
 * accessed in a per event, state and transition manner and they can have default or non-default value. 
 * The minimum interface that an attribute template parameter must provide, is given in 
 * faudes::AttributeVoid. Derived attribute classes are meant to provide addtional semantics, eg 
 * faudes::AttributeFlags for boolean flags and faudes::AttributeCFlags for controllability properties. 
 * The TaGenerator transparently supports extended attribute semantics, but does not provide 
 * taylored access functions. This is done in TaGenerator
 * derivates eg TcGenerator.
 *
 * Technical detail: Attributes data types must be derived from AttributeVoid, which in turn is derived from 
 * the general purpose base faudes::Type. For your derived attribute class to be fully functional, 
 * you must reimplement the faudes::Type::New().
