> The {{ExtractCCDAAttributes}} Processor uses a custom {{CDAUtil}} class to load and parse the FlowFile {{{}InputStream{}}}. The {{CDAUtil}} class also includes a {{load}} method that takes a standard DOM {{{}Document{}}}. The Processor should be updated to use the standard {{nifi-xml-processing}} library for parsing the XML prior to calling {{{}CDAUtil.load{}}}.
> In addition to implementing standard XML parsing, the {{ExtractCCDAAttributes}} Processor should be deprecated for removal because the implementation relies on outdated libraries, and the extensive use of FlowFile attributes does not align with best practices for record-oriented data handling.
