Test Case taDOM2/23-taDOM2-31-DC

taDOM2 Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns Node

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Behavior specified with base operations:

readCO
modifyCOLCE
modifyLCNSE

Read Set = CO , Write Set = COLCE LCNSE

taDOM2 Lock Requests of checked Operation deleteNode(contextNode) executed on node DC

The deleteNode operation is executed on the context element node CO (an arbitrary child of PA) and deletes the context node. Previous and next sibling nodes are existing.

Bahavior specified with base operations:
