If there is a failure in 'XSLTProcessor->transformToURI()' (it returns false) is nothing written to the file specified? I ask because I'm implementing a caching system. I'm having the output written to a cache file and want to be guaranteed that in case of error, the specified file remains as it was before the operation. In other words, I'd like the destination file to be written to IF and ONLY IF the transformation is successful. Is this the case?
