> IdentifyMimeType uses tika configured with a custom-mimetypes.xml\[1] to specify (among others) the flowfile-v* mime types. However, these do not include priorities. Therefore, a NiFi FlowFile V3 package with a payload containing, for example, html including the string:
> {code}
> <html xmlns=
> {code}
> will be identified as "application/xhtml+xml" \[2] which, while matching the pattern, is not as correct as identifying it as application/flowfile-v3. To fix this, I believe we need to specify a higher priority for the FlowFile V3 "magic"...
