* 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.
