The following provides an example of bpelx:append syntax in a BPEL project that supports BPEL version 2.0. In BPEL 2.0, the functionality is the same as described in bpelx:append in BPEL 1.1, but the syntax is slightly different.

<bpel:assign>
   <bpelx:append>
      <bpelx:from>$billOfMaterialVar/b:parts/b:part</bpelx:from>
      <bpelx:to>$consolidatedBillOfMaterialVar/b:parts</bpelx:from>
   </bpelx:append>
</bpel:assign>
