+//! This allows you to use the Connected Interactive
+//! Object without having to recalculate presentation,
+//! selection or graphic structure. These are deduced
+//! from your reference object.
+//! The relation between the connected interactive object
+//! and its source is generally one of geometric transformation.
+//! AIS_ConnectedInteractive class supports selection mode 0 for any InteractiveObject and
+//! all standard modes if its reference based on AIS_Shape.
+//! Descendants may redefine ComputeSelection() though.
+//! Also ConnectedInteractive will handle HLR if its reference based on AIS_Shape.
