<Dependency> element

<Dependency> elements play a special role in a BEADL task description since they can be defined as child elements for different element types. Such an element allows the corresponding parent element only to be added to the task description if a specified criterion is met.

<BeadlXmlElement >
  <Dependency type="DepedencyType" expression="Criterion" />
</BeadlXmlElement>
