Issue Summary

The documentation for Create Permission Scheme Jira REST API does not clarify the mutually exclusive condition for 'parameter' and 'value'.

The API documentation should be updated to clarify that either one of the parameters is required.

Steps to Reproduce

1. Use the payload from the "Example" code for the create Permission scheme.
2. The body for the POST method has both "parameter" and "value":

   "holder": {
           "parameter": "jira-core-users",
           "type": "group",
           "value": "ca85fac0-d974-40ca-a615-7af99c48d24f"
         } 

Expected Results

A permission scheme should be created using the example code from the documentation.

Actual Results

The API call will fail with below message:

    "errorMessages": [
        "The body parameters 'parameter' and 'value' are mutually exclusive."
    ],
    "errors": {} 

Workaround

The body should either contain a "parameter" or "value"
