Attribute |= expression |
|
To make is easier to write rules succinctly, you may use the assignment:
TheAttribute |= expression;
... which sets TheAttribute to true if it is already true, or if the expression is true.
For example:
Urgent |= ^any(child,Urgent)
A project is urgent if it's been declared to be urgent itself, or if any child is urgent
