Using XPath functions in the BPEL Process manager

When using XPath expressions in XSLT, and you want to use one of the following functions:

• getProperty(propertyName as string)
• setCompositeInstanceTitle(titleElement)
• getComponentInstanceID()
• getComponentName()
• getCompositeInstanceID()
• getCompositeName()
• getECID()

You can use these in the Oracle Mediator XSLT mapper only, and not Oracle BPEL Process Manager. For Oracle BPEL Process Manager, you have to  use an assign activity.
