> There is a logic in MimeTypes class to return text/plain for corrupted xml files not detected as text/html here: https://github.com/apache/tika/blob/324f2f2ccff21c608969e2e79da88e71379a58dc/tika-core/src/main/java/org/apache/tika/mime/MimeTypes.java#L281
> I think this should be changed to return application/xml, even if the file is corrupted, like is done for all other mimetypes, being more consistent across file formats. Even if a jpg or doc file is corrupted, image/jpg or application/msword is returned.
> I have about ~2k from ~90k xml files in an internal corpus that trigger this.
> If other fellow devs agree, I can submit a patch and unit test.
