You don’t understand the concept of “meta-formats”? Maybe you prefer 
“format family” or “format superclass”. Does that help make things 
clearer? It is something easily specialized to become an application-
specific format, with less effort than creating the specific format from 
scratch.

An earlier example is XML. Also IFF on the Commodore-Amiga, from the 
1980s.

Does that help?
