If language is not Java, then Extractor framework is used to look up a extractor provider to create extractor from the expression. Parameter list is a comma separated list of parameter names, parameters not used in the condition expression can be omitted. E.g. parent, child, sibling or, if child is not used in the condition expression parent,,sibling.
