Improved "external-text-formatter" test case helper template

* test cases should also provide examples of how the tested external functions may be integrated into transformations
** helper templates such as "formatter" or "transformer" are an important step into this direction
** especially functions other than plain read-only functions fit much better into a template context than a XPath context
