  Test Case taDOM3+/26-taDOM3+-3-PS
taDOM3+ Lock Requests of executed Operation prependChild(contextElementNode, childType, childValue) returns NodeThe prependChild operation is executed on the context element node CO and prepends a new child. The context element node CO has still no child nodes before this operation. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the now only child) is returned.
Behavior specified with base operations:- readCO
- modifyCOFCE
- modifyCOLCE
Read Set = CO , Write Set = COFCE COLCE - LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]
taDOM3+ Lock Requests of checked Operation getPrevSibling(contextNode) executed on node PSThe getPrevSibling operation returns null because the context node CO is the first child of parent node PA and no previous sibling node PS exists.
Bahavior specified with base operations:Read and write sets for execution on PS:Read Set = PS PAFCE , Write Set = - LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on PS
- LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-] on PS
Operations must be compatible| Check | Existing LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]

Requested LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on PS | Requested lock IR on AC compatible to existing lock IX.
Requested lock IR on PA compatible to existing lock IX.
