===== Limitations of SysML v1 =====
  - Lack of integration between structure and behavior (e.g., flows, triggers, input to do/behavior)
  - Limitations of executing behavior that is integrated with structure/ports
  - Lack of integration between different kinds of behavior (seq, act, stm, uc, timing)
  - Lack of integration with analysis expressions so that it is simple to create an expression anywhere in the model
  - Unification of expressions and constraints
  - Inability to represent structure of I/O and how they are input to different functions
  - Lack of representation of timelines
  - Inability to easily create and destroy relationships such as connectors
  - More flexible pre/post conditions using bdd/instance diagrams (refer to Keith Butler presentation)
  - Support for software architecture concepts as identified by Ron Townsend
  - Support for variant behavior modeling concepts
