Use Case 14:

Node Operation getValue(contextAttrNode)
returns Node

The getValue operation executed on the attribute context node CA of an arbitrary element node CO returns the string node AS appended to the attribute node that represents the actual node value.

This operation cannot be executed on an element context node
This operation cannot be executed on an text context node
