Subject: Revamped external function result trees * the root node of the result
 tree of each function is a domain element ** i.e. the root node of
 "read-xml-file" is "file", the root node of "read-directory" is "directory" *
 the root node contains the result state of the function call encoded in a
 "result" attribute ** possible values are "success" and "error" ** the root
 node may contain additional attributes such as the target path of a called
 transformation * the actual function result is contained within the child
 nodes of the function root node ** i.e. the XML file tree returned by
 "read-xml-file" is a child of the function root node ** if specific errors
 occured they are also returned as child nodes of the function root node ***
 this is currently only the case for "transform" where transformation errors
 are returned as "error" value node childs of the function root node * updated
 test cases accordingly
