+  * 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 chosen 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.
