Subject: Implemented transformation execution function *
 InputXSLT::PlattformGuard handles xerces and xalan construction and lifetime
 * InputXSLT::TransformerGuard instantiates PlattformGuard, configurates
 external functions ** offers execute method for "executing" a XSL
 tranformation with empty input
