    \brief A behavioral feature is a feature of a classifier that specifies an aspect of the behavior of its instances.A behavioral feature is implemented (realized) by a behavior. A behavioral feature specifies that a classifier will respond to a designated request by invoking its implementing method.A behavioral feature owns zero or more parameter sets.
