## Jpeg2000 Tags

The tags below are extracted from JPEG 2000 images, however ExifTool currently writes only EXIF, IPTC and XMP tags in these images.

> 'xml ' | XML | undef!+ | --> XMP Tags (by default, the XML data in this tag is parsed using the ExifTool XMP module to to allow individual tags to be accessed when reading, but it may also be extracted as a block via the "XML" tag, which is also how this tag is written and copied. This is a List-type tag because multiple XML blocks may exist)
