+  Send a custom request to an LSP linter. The arguments are defined as
+  follows:
 
-  `buffer` must be a valid buffer number, and `linter_name` is a |String|
-  identifying an LSP linter that is available and enabled for the |filetype|
-  of `buffer`. `method` is a |String| identifying an LSP method supported by
-  `linter`, while `parameters` is a |dictionary| of LSP parameters applicable
-  to `method`. `Callback` is a |Funcref| that is called when a response to the
-  request is received, and takes as unique argument a dictionary representing
-  the response to the request obtained from the server.
