The following MIME types are usually implemented:
* text/plain
* text/html
* text/markdown
* text/latex
* application/json
* application/javascript

* image/jpeg
* image/svg+xml
Parameters
----------
obj : object
The Python object whose format data will be computed.
include : list, tuple or set; optional
A list of format type strings (MIME types) to include in the
format data dict. If this is set *only* the format types included
in this list will be computed.
exclude : list, tuple or set; optional
A list of format type string (MIME types) to exclude in the format
