A lane is a subdivision of a pool that is used as a container for partitioning processes. How you use lanes is specific to your business. A lane can be Normal or
Closed. The contents of a normal lane are visible. The contents of a closed lane are not visible and are used for "black-box" processes where you do not know the details of the contained processes.
Unlike any text that you enter on the Description tab in the Properties view for an object, text annotations are displayed directly on the process.
