Use Case 17:

Node Operation setValue(contextElementNode, valueString)
returns Node

The setValue operation executed on the context element node CO returns the modified context element itself. In taDOM2(+) the CX lock on PA must be requested additionally in order to prevent an execution of the getChildNodes() method on the parent node.

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

Scenario 17-1 for taDOM2 Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CN	SX	-	-	-	-
PA	CX	-	-	-	-

Scenario 17-2 for taDOM2+ Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CN	SX	-	-	-	-
PA	CX	-	-	-	-

Scenario 17-3 for taDOM3 Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NX	-	-	-	-

Scenario 17-4 for taDOM3+ Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NX	-	-	-	-
