Detailed Description

Classification of scope describe by A towards B.

The leaf-node of A defines the root of a subtree in the DDExpandedView, so does the leaf-node of B.

• returns different_branch, if the leaf-node of A defines a different subtree than the leaf-node of B
• returns subtree, if the leaf-node of A is in the subtree rooted by the leaf-node of B
• returns supertree, if the leaf-node of B is in the subtree rooted by the leaf-node of A
