/**
  * This class implements the interface XInteractionRequest. Instances can
  * be passed directly to XInteractionHandler::handle(...). Each interaction
  * request contains an exception describing the error and a number of
  * interaction continuations describing the possible "answers" for the request.
  * After the request was passed to XInteractionHandler::handle(...) the method
  * getSelection() returns the continuation choosen by the interaction handler.
  *
  * The typical usage of this class would be:
  *
  * 1) Create exception object that shall be handled by the interaction handler.
  * 2) Create InteractionRequest, supply exception as ctor parameter
  * 3) Create continuations needed and add them to a sequence
  * 4) Supply the continuations to the InteractionRequest by calling
  *    setContinuations(...)
  *
  * This class can also be used as base class for more specialized requests,
  * like authentication requests.
