Javadoc

Walks the elements of a BpmnModelInstance and invokes the provided ModelElementVisitor for every element.

The following order is guaranteed (anything that is not listed here is not guaranteed):

An element is visited only after its parent has been visited (top-down)
An element's child is visisted before any not yet visited sibling (depth-first)

We can add more constraints to this as we see fit (e.g. certain BPMN elements in the same scope can be visited in a defined order to make transformation more convenient)

Depth-first is nice for transformation so we can have some kind of stack with transformation state.
