> The {{TransformXml}} processor supports Secure Processing as of NiFi 1.3.0,
> which prevents external access attempts using XML entity references. The
> {{Secure Processing}} property applies to input FlowFiles, but does not apply
> to the XSLT source that the processor uses during transformation.
> {{TransformXml}} should be updated to apply Secure Processing to XSLT sources.
