==SysML Model Elements⌘==<br />
===Comment⌘===<br />
[[File:ClipCapIt-160720-130514.PNG]]<br />
* Comments can be associated with any model element and are quite useful as an informal means of documenting the model. <br />
* SysML has introduced extensions to a comment called: '''Rationale''', '''Problem''' and '''ElementGroup'''<br />
====Problem and Rationale⌘====<br />
[[File:ClipCapIt-160720-131020.PNG]]<br />
* A '''Rationale''' is used to facilitate the system modeler in capturing decisions.<br />
* The rationale may be attached to any entity, such as a system element (block), or to any relationship, such as the satisfy relationship between a design element and a requirement.<br />
* A '''Problem''' documents a deficiency, limitation, or failure of one or more model elements to satisfy a requirement or need, or other undesired outcome. It may be used to capture problems identified during analysis, design, verification, or manufacture and associate the problem with the relevant model elements.<br />

====Element Group⌘====<br />
[[File:ClipCapIt-160720-131223.PNG]]<br />
* The '''Element Group''' provides a mechanism for grouping various and possibly heterogeneous model elements by extending the capability of comments to refer to multiple annotated elements. <br />
* It can group elements that are associated with a particular release of the model, have a certain risk level, or are associated with a legacy design. <br />
* The semantics of ElementGroup is modeler-defined, the body text is not restricted. <br />
* It can describe the grouped elements as well as elements or values related to the grouped elements.<br />

* Constraints are used to capture simple constraints associated with one or more model elements</div>Fstachecki
