Revamped external execute function into a external text formatter function

* importing XML output of a called executable into the result document required special logic which clashed with a general execute function
* general execute function may be implemented in the future
** support for external text formatters with XML output has a higher priority
* current implementation enables calling a markdown parser and including the XHTML output into the document
