Use Case 20:

Node Operation setAttribute(contextElementNode, ctxAttrNameString, valueString)
returns Node

The setAttribute operation is executed on the context element node CO and sets a new value of the context attribute node CA. The named context attribute already exists and the operation returns the value node AS.

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

Scenario 20-1 for taDOM2 Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CN	NR	-	-	-	-
CA	NR	-	-	-	-
AN	NR	-	-	-	-
AS	SX	-	-	-	-

Scenario 20-2 for taDOM2+ Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CN	NR	-	-	-	-
CA	NR	-	-	-	-
AN	NR	-	-	-	-
AS	SX	-	-	-	-

Scenario 20-3 for taDOM3 Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CA	NR	-	-	-	-
AS	NX	-	-	-	-

Scenario 20-4 for taDOM3+ Lock Requests:
Node	Lock	PSE	NSE	FCE	LCE
CO	NR	-	-	-	-
CA	NR	-	-	-	-
AS	NX	-	-	-	-
