The slide shows how the ElementGroup can be extended using custom stereotypes, based on a simplified form of the Webel Parsing Analysis recipe for SysML®.
We are also going to take a walk on the dark side:
The basic UML Document (an Artifact) from the UML standard profile has been extended to include a
url:String attribute. This extended Document (which also has the keyword «document») can then act as the mandatory
source:Document of a Snippet (with keyword «snippet»), which is a customised extension of ElementGroup.
