-Fragment Selectors use the fragment part of the URI specification to define a selection mechanism for parts of resources. The definition of the representation's media type specifies the structure of the value of the fragment. This is commonly used in IIIF to include the media fragment syntax of `xywh=<x>,<y>,<width>,<height>` to define a 2 dimension region.
