sometimes a red triangle appears over some (not all!) of my requirement artifacts that I have constructed before starting more detailed UML work and development.
I have no idea what causes it or what it is meant to express. What's more, I cannot get rid of it. ;)
As far as I know this has nothing to do with the UML or SysML specification - or does it?
Can anyone explain?
Thanks :)
It has nothing to do with UML or SySML. What is says is that someone bookmarked the element. You may have done so by accident by pressing shift-spacebar.
If you search the help file for "Manage Bookmarks" you will get the full explanation.
