Transitions are the connections between workflow steps. They control
the overall progress of the workflow. There is no limit to the number
of transitions you can draw going into a step or out of a human step.
Each automatic step has a predetermined number of transitions that
can go out of it.
Use transitions to give users choices when Human steps are completed.
For example, if one user is reviewing a translation, you can give
that user the option of returning the task to the translator for corrections,
or approve the translation and move the workflow along.
When you draw a transition in the Workflow Editor, WorldServer checks
rules and return values and does not allow you to save a workflow
if there are errors in transitions between workflow steps. Automatic
steps, for example, have a set number of return values. You must draw
one transition for each return value from the step. Human steps require
text to correlate with the transition.
