+    @short      handle interactions non visible
+    @descr      Sometimes it's necessary to use a non visible interaction handler.
+                He can't do anything, which a visible one can handle.
+                But it can be used to intercept problems e.g. during loading of documents.
+
+                In current implementation we solve conflicts for following situations only:
+                    - InteractiveIOException
+                    - InteractiveAugmentedIOException
+                All other requests will be aborted.
