The bpelx:rename extension in an assign ACTIVITY enables a BPEL process to rename an ELEMENT through use of XSD type casting.

The syntax of bpelx:target is similar to and a subset of to-spec for the copy operation. The target must return a LIST of one more element nodes. Otherwise, a bpel:selectionFailure FAULT is generated. The element nodes specified in the from-spec are renamed the QName specified by the elementTo attribute. The xsi:type attribute is added to those element nodes to cast those elements to the QName type specified by the typeCastTo attribute.

Assume you have the following employee list:

JohnDole
JaneDole
PeterSmith
MarySmith

Promotion changes are now applied to Peter Smith in the employee list:

After executing the above casting (renaming), the data looks as follows with xsi:type info added to Peter Smith:

JohnDole
JaneDole
3000
marysmith

The employee data of Peter Smith is now invalid, because and are missing. THEREFORE, is used to add that information.
