The BPEL script is responsible. BPEL can be considered a programming
language and in the HelloWorld example it is used to compose the hello
world string. Have a look at the .bpel file and you will see an assign
activity that uses XPath for that string manipulation.

Have a look at http://en.wikipedia.org/wiki/BPEL for some (partially
wrong) background information or just skim through the specification
