Stereotypes <<invokes>> and <<pr

[cerevro]

In the Use Case Relationships toolbox i can see the relationships invokes and predeces, i looked for it at UML Superstructure Specification, but i find nothing, does someone knows what are intended for ?

See 'Use Case'->'Elements and Connectors'

'Note: Invokes and Precedes relationships are defined by the Open Modeling Language (OML).'

Sparx EA supports the Iconix approach to UML modeling for Use Case Diagrams whereby "invokes" and "precedes"  are a superset of "includes" and "extends" in Use Case diagrams as the use of these stereotypes are (supposed to be) easiler to understand by "non-uml experts" as they don't have to concern themselves with the direction of the arrow between use cases, as is the case (no pun intended) with "includes" and "extends"

More information can be found in the following book:
Use Driven Object Modeling with UML Theory and Practice
which speaks to the Iconix approach to UML requirements/requirements realization modeling
