' Scope: Interactions in an enterprise, software system or container.
' Primary and supporting elements: Depends on the diagram scope -
'     enterprise - people and software systems Related to the enterprise in scope
'     software system - see system context or container diagrams,
'     container - see component diagram.
' Intended audience: Technical and non-technical people, inside and outside of the software development team.

' Dynamic diagram introduces (automatically) numbered interactions:
'     (lowercase) increment($offset=1): increase current index (procedure which has no direct output)
'     (lowercase) setIndex($new_index): set the new index (procedure which has no direct output)
'
'     (Uppercase) LastIndex(): return the last used index (function which can be used as argument)
'     (Uppercase) Index($offset=1): returns current index and calculates next index (function which can be used as argument)
'     (Uppercase) SetIndex($new_index): returns new set index and calculates next index (function which can be used as argument)
