How do I mix it?

>    Beyond plain text, there are many formats for representing what might
>    be known as "rich text".  An interesting characteristic of many such

>    the software that interprets them.  It is useful to distinguish them,
>    at the highest level, from such unreadable data as images, audio, or

Org is not just rich text for reason as explained here:
https://datatracker.ietf.org/doc/html/rfc6838#section-4.2.5 so I
suggest reading it.

Examples of content types for some "rich" text formats:

.odt 	OpenDocument text document
application/vnd.oasis.opendocument.text

.rtf 	Rich Text Format (RTF) 	application/rtf

.xhtml 	XHTML 	application/xhtml+xml

xml 	XML 	application/xml is recommended as of RFC 7303 (section
4.1), but text/xml is still used sometimes. You can assign a specific
MIME type to a file with .xml extension depending on how its contents
are meant to be interpreted. For instance, an Atom feed is
application/atom+xml, but application/xml serves as a valid default.

Review definition of "application/*" type.
